I want a personal chatbot connected to my own WhatsApp number that quietly reads new messages throughout the day, then sends me one concise end-of-day summary straight back into the same chat. Although the bot must be authorised to access my Yahoo Mail inbox (IMAP/POP or official API) as well as my WhatsApp messages, the only content it should actually condense and report is the WhatsApp conversation stream; email access is purely so the system can sit in the background ready for future extensions. Key points to build in: • Secure sign-in to Yahoo Mail and WhatsApp (QR pairing / Meta Cloud API or a dependable open-source library). • Local or server-side NLP that extracts key topics, action items and unanswered questions from WhatsApp messages, then formats them into a sh...
I am searching for a programmer to make a robot to deal on Polymarket website. Specifically the crypto market for the BTC 5 minutes and all the other criptos at the 15 minutes trade. The robot must trade in all these markets at the same time. Must understand from where the Polymarket get the information for the value they shows (it is not what we see live and it is not from what we see the link they post). Must be able to build a admin panel for small adjustments until we get the perfect point of trading. I am pretty sure that it won´t win all the bets, as I saw the results of some other robots working. But, at the end of the day, must have done some profit. You tell me what you´ve done, and let´s get it tuned for this market.
I have a Telegram-based social media bot together with its admin panel that now needs to be moved from local development to a live server. The job is split in two clear parts: • Deployment: set up the production environment, install the bot and its admin panel, configure all services (webhook, database, SSL, background workers if any) and confirm everything runs smoothly under the chosen domain or IP. • Improvements: – Fix existing features that are currently throwing errors or behaving inconsistently. – Update the bot’s appearance, so the end-user interaction on Telegram looks polished and on-brand. You’ll hand back a fully functional bot, an accessible admin dashboard, and concise setup notes so I can reproduce the installation if I ever migrat...

I need an automation-focused cloudbot installed and fully configured on my private VPN server. The server is already up and running; what I’m missing is the bot layer that can execute scripted jobs reliably and remain reachable through the VPN’s secure tunnel. Here’s what I expect from you: set up the bot framework (Python or Node.js with Docker is fine—use what you’re fastest with), connect it to the server’s existing environment, harden the configuration for security, and leave me with clear, step-by-step documentation so I can add or adjust tasks later on. Once you’re done, the bot should start automatically on reboot and log its activity to a file I can review. If you’ve deployed similar automation bots before and are comfortable workin...
I need a Python application that takes a pretrained YOLO model and turns it into a real-time desktop solution capable of recognising industrial, hand and power tools as they appear in a live camera feed. The workflow should be straightforward for a non-technical operator: launch the program, select the camera (USB or built-in), and immediately see bounding boxes with class names and confidence scores updating on-screen at 30 fps or better. Key details • Model: start with an existing YOLO checkpoint (v5, v7, v8 or YOLO-NAS—whatever you feel offers the best speed / accuracy trade-off). Feel free to fine-tune if that improves precision, but the core must stay YOLO. • Language & libs: Python 3.x, OpenCV for video capture/rendering, torch or ultralytics for inference. ...

I need a clean, well-documented Python module that hooks into the official Upstox SDK and gives me one-call access to full trading execution. The code must let me place Market, Limit and Stop orders programmatically, then track and manage those positions with built-in risk controls—Stop-loss, Take-profit and Trailing-stop—triggered server-side whenever possible. My current environment already runs on Python 3.10, so your solution should slot straight in with minimal external dependencies beyond the Upstox client library.

I have too many incoming enquiries to keep qualifying each lead and slotting them into my calendar by hand, so I want an end-to-end AI automation that takes a prospect from first contact right through to a confirmed appointment. Here’s the flow I picture: 1. A prospect submits a web form or replies to a social DM. 2. An AI layer asks a short set of qualifying questions, scores the answers, and decides whether the person fits my criteria. 3. Qualified leads are shown my real-time calendar, pick a slot, and receive confirmation plus reminders. Unqualified leads are thanked and redirected. 4. All conversations, scores, and bookings should be logged in my CRM, and I need a simple dashboard to tweak the questions or scoring rules. Feel free to use the stack you’re most productive ...
I’m setting up a government-supported cybersecurity SaaS that serves Emirati organisations through the MZN x Hub71 Programme. The vision is to release an MVP that focuses first on automated threat detection and user-facing awareness dashboards, then iterate toward fuller capabilities such as data encryption and advanced authentication. I’m offering true co-founder equity rather than a contractor fee, so I need a senior expert who can own the entire technical stack from Day 1, move fast, and help shape product-market fit. You’ll choose the architecture, assemble the initial codebase, and have freedom over tools—whether that’s AWS, Azure, GCP, Kubernetes, Python, Go, or whatever you believe will let us ship reliably and scale inside the UAE. The immediate goal...
My PHP-based CRM already pushes one-way notifications through our integrated SMS gateway. I now need two key enhancements: 1. Assign one dedicated, system-level outgoing phone number that the code uses automatically for every SMS we send. 2. Capture incoming replies on that same number so our staff can read and respond inside the CRM. While adding this, please also log and display the delivery status (delivered, failed, pending) for each message in an easy-to-read field or column. The gateway APIs are fully functional and documented; you’ll extend the existing PHP modules, database tables, and any necessary webhooks to make the process seamless. Clean, well-commented code and a brief implementation note are the final deliverables.
I need to connect our custom-built PHP CRM to Gmail so that every message—across all email folders—syncs seamlessly into our system. Incoming emails should be stored against the relevant contact, and I want to be able to compose, send, and reply directly from the CRM interface. Key requirements • Use the official Gmail API with OAuth 2.0 so users can grant access securely. • Pull full message content, attachments, and metadata while capturing read, unread, replied, and forwarded statuses. • Write clean PHP code that fits our existing MVC structure and respects current database schemas. • Maintain two-way sync: actions taken in Gmail (read, delete, label) should reflect in the CRM, and vice versa. • Provide clear setup instructions plus a br...

I need a lightweight, AI-flavoured MVP that lets volunteers log and track the hours they devote to our projects, all from a single web dashboard. The build should feel modern and “smart” in its UX—think quick, predictive form fills and clean analytics rather than heavy-handed machine-learning features. Core scope • Hours-tracking module: volunteers enter time, edit past entries, and view personal and aggregate stats. • Instagram tie-in: pulling our hashtagged posts into a simple feed on the dashboard and giving admins one-click sharing of top volunteer highlights back to Instagram. OAuth-based sign-in is fine; no need for Facebook or Twitter right now. • Admin view: exportable CSV of logged hours plus a concise summary panel showing totals by volunte...
Title: AI-Powered Document Intelligence Demo – 7-Day Delivery Budget: ₹10k Timeline: 7 Days Location: Remote ⸻ Project Overview We are building a proof-of-concept Doc Intelligence demo for medical perfusion sheets. The goal is to extract structured vitals from uploaded images/PDFs and display them in a simple real-time dashboard with alerts.

OCR / Text Extraction • Input: scanned perfusion sheet (PNG/JPG) or PDF. • Output: structured JSON (BP, ACT, Flow, Temp, Time). • Include basic validation (range checks, missing values). 2. Backend API • Python + FastAPI (or equivalent). • Receives uploaded file → returns structured JS...
Throughout this semester I will be submitting weekly homework problems that touch on core computer-science topics—mainly programming fundamentals, classic and advanced algorithms, and data-structure design and analysis. Every task is written for Python, so clear, idiomatic code and the ability to explain your approach in that language are essential. Typical homework sets range from short coding snippets to multi-function scripts that must run cleanly from the command line. Beyond simply providing a working solution, I need concise inline comments and a brief write-up that outlines the algorithmic choices and Big-O reasoning so I can learn from the submission. Deliverables for each assignment • A .py file (or files) that executes without external dependencies beyond the stand...
1. Developer will use JUCE (C++). This code serves as the "Bridge" logic. -Background Thread to talk to Python. Background Thread Logic to talk to Python, The FIFO Buffer Strategy The Python Bridge. I have the C++ Bridge Logic. Developer Implementation Details 1. The "FIFO" Buffer (First-In, First-Out)In C++, you cannot simply stop the audio clock. The developer must implement a FIFO Buffer. This collects the "dry" audio chunks from the DAW and holds them until the Python engine is ready to swallow the whole file. 2. Communication ProtocolFor the "Hybrid" version, the developer has two choices for how C++ talks to Python:File-Based (Easier): C++ writes $rightarrow$ Python processes $rightarrow$ C++ reads out.wav.Socket-Based (Pro): C++ sends ...
I want to build a sophisticated cryptocurrency arbitrage program that scans several major exchanges—Binance, Coinbase, Kraken, or any others you judge more profitable—in real time, pinpoints price discrepancies, and executes trades automatically. My target is an 80 %+ win rate, so the core logic should combine fast order-book scraping with an AI-driven decision engine that filters for the highest-probability spreads before committing capital. The application must stream data with minimal latency, place and manage orders end-to-end, and keep me fully informed through a clean analytics dashboard showing live PnL, historical performance, and risk metrics. Flexibility to plug in additional exchanges later is important, so please structure the code modularly (I’m fine with Py...
I’m putting together a fully local pipeline that can turn text or microphone input into real-time synthetic video with out latensy and matching speech without ever calling a paid API. What I need from you is a clear, reproducible worksheet that walks me from a blank machine to a working demo. My main pain-point is model selection and setup, so the document has to name the exact models, versions, weights and repos you recommend (Stable Diffusion / Stable Video Diffusion or similar on the visual side, plus an open-source TTS or voice-cloning stack). Everything must run on a local Linux server with an NVIDIA GPU, CUDA and Python—no external SaaS calls. Please include any build flags, environment variables, VRAM tips and latency-saving tricks that actually matter in practice...
Title: Senior Android Developer: Multimodal AI Pipeline (Real-time Video & Audio) **Project Description:** We are seeking a Senior Android Engineer to develop a modular, high-performance infrastructure for **real-time Multimodal capture (Video + Audio)**. The core of the project is a "Hybrid AI Routing Engine" that intelligently switches between on-device local processing and cloud analysis using Gemini 2.0. This application is an R&D prototype that must be **Play Store Ready**, with a heavy focus on background stability and thermal management. **Important:** The ultimate goal is to port this architecture to an Android-based smart glasses OS (AugmentOS), so the code must be hardware-agnostic. **Technical Specifications:** **1. Multimodal Pipeline (Camera + Audio):** ...
My workbook already asks SerpApi for data the moment I type a model number in the “Model” sheet, and Power Query pushes the results into the “Result” sheet. Two nagging issues stop it from being production-ready: 1. The cache sheet that should store the API response has stopped working, so every look-up now triggers a new, slow call instead of re-using the last fetch. 2. On the “Result” sheet the sale price reaches the correct cell, but the regular (full) price column stays empty. I need someone who understands Power Query, Excel data model, and REST/API connections (SerpApi in particular) to: • Diagnose and restore the caching logic so the workbook re-uses previously fetched JSON. • Update the query/transform steps so the full price fi...
My company needs a straightforward invoicing application that we can either host in a browser or install on office desktops—whichever you feel is the leanest route. Core requirements are simple but non-negotiable: every invoice must calculate taxes automatically according to rates I configure, and the system has to keep a searchable customer database so future bills pull the right details instantly. All invoices will be produced manually from an on-screen form; there is no need to connect to live sales data or set up scheduled runs. If you choose a web stack, I’m happy with a standard LAMP/MEAN approach or something in Django, Laravel, or ASP.NET—use whatever lets you deliver a clean UI and reliable performance. If you prefer a desktop build, a lightweight Electron, .N...
I want a lightweight CRM that lives in Google Sheets and is fed by a Google Form. When a new lead is submitted through the form, the data should flow straight into a master sheet, automatically assign a unique ID, and show up on separate tabs that reflect our sales-tracking focus. The only metric I care about right now is where each lead sits in the pipeline. I have draft stages but I’m open to your suggestions if there’s a cleaner way to visualise progress. What matters is that I can move a lead from one stage to the next with a simple dropdown or checkbox and have that change reflected everywhere else instantly. Key needs • Google Form → Google Sheets integration with zero manual copy-paste • A clear pipeline board or dashboard that updates in real time as ...
I need a seasoned technical writer who can turn a set of design notes, log outputs and performance metrics into a clear, well-structured technical report for a Software/IT audience. The material will cover system architecture, component interactions and benchmark results; accuracy and a logically layered explanation are more important to me than marketing polish. You will be working from source material I provide—architectural diagrams, API specs, interview transcripts with developers and some raw CSV data—so an ability to distill complex information and cross-check for consistency is essential. Familiarity with common tooling such as Markdown, LaTeX or Word (your choice) plus diagram utilities like , Visio or PlantUML will make the process smoother. Deliverables •...

I want to deploy a fully-functional AI assistant built on a free Chinese open-source model—Qwen 2.5, Minimax01, Kimi 1.5 or Open Manus are all acceptable. Phase one is crystal-clear: the system must start producing qualified leads for short-term business loans, bridge loans, consolidation loans, equipment financing, commercial refinance and purchase, and even grant-seekers. Accuracy, compliance, and the ability to track every interaction matter more to me than flashy extras. Here’s how I picture the first release: • Model integration and fine-tuning on my loan-specific prompts and historical data • A lead-generation workflow that scrapes or ingests approved data sources, segments prospects, and outputs clean CSV or pushes directly into my CRM • Simple das...
I have an AI agent built with n8n, OpenRouter (ChatGPT 5.2), Browserless, RapidAPI, Google Sheets, and Squarespace integration. It was working correctly before another developer made changes. The system must be fully restored and optimised. What You Must Do - Fix the workflow error that is preventing the agent from responding (a webhook in another workflow is throwing an error and blocking execution). - Restore full agent functionality so it responds correctly on the WEBSITE (n8n preview does not count — only website behaviour matters). - Reduce website response time to under 60 seconds on the website, again n8n preview does not count — only website behaviour matters (it previously responded in ~60–70 seconds before changes were made). - Investigate scraper logic and...
I’ve built the bones of our workspace, but the boards don’t quite talk to each other the way I imagined. Automations fire inconsistently, the reporting widgets don’t reflect real-time data, and the overall flow feels clunky instead of intuitive. I need a fresh set of expert eyes to: • Audit the existing boards, columns, dependencies and integrations • Re-engineer the key automations so items move, notify and update reliably • Rebuild or fine-tune dashboards so metrics and charts refresh accurately and are easy to read at a glance Acceptance criteria – All critical automations trigger 100 % of the time during testing – Dashboards pull from the correct boards without manual refreshes – Workflow from item creation to completion...
I’d like to partner with a skilled cryptocurrency trader who can reliably turn a starting stake of about ₹100 per position into roughly ₹300. The core pairs I want you to trade are BTC/ETH, BTC/USD, and ETH/USD. If you spot a compelling edge in a different pair, feel free to propose it—my risk tolerance is flexible as long as the path to tripling the capital makes sense. Tell me, in plain terms, the strategy you’ll follow, the exchange and tools you prefer (e.g., Binance, Bybit, TradingView, Python bots, etc.), and how you’ll keep me in the loop on entries, exits, and portfolio status. I’m open to conservative, balanced, or aggressive tactics if the reasoning is clear and the numbers add up. Deliverables • An upfront plan outlining indicators, pos...
I built a cross-platform application that talks to my custom ESP32 controller and drives an ultrasonic record cleaner. It works, but it is still very much a prototype. I now want to move it a step closer to a polished, production-ready tool. User-interface improvements • Navigation & layout – The current screen flow works well, but needs a few enhancements such as tallying total cycles and changing temp settings from % to degrees C or F • User feedback & interactions – The app already shows real-time status (temperature, cycle countdown, tank level) . Need notifications near cycle ends with subtle haptics or unobtrusive toast messages are welcome where supported. Functional enhancements • New features – We're planning to add more adva...
Title=AWS Engineer Needed – Deploy Containerized Multi-Agent OpenClaw System (Slack + Telegram + E2B + Model Routing) – 1–2 Day Build ⸻ READ THIS CAREFULLY If you have not personally deployed containerized services in AWS (ECS or EC2 + Docker), configured IAM correctly, and implemented Slack OR Telegram bot integrations before — do not apply. Generic AI-written proposals will be ignored. This is a 1–2 day implementation for someone who knows AWS and event-driven systems. ⸻ Project Summary I am building a small internal “AI Office” composed of multiple OpenClaw agents: • Orchestrator • Marketing agent • Research agent • Ops agent Each agent must run as a containerized service in AWS and communicate via SQS (or EventBrid...
I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliver...
