I’m assembling a real-time dashboard solution that must run smoothly on both web browsers and mobile devices. The front end will be built with modern HTML, CSS and vanilla JavaScript where appropriate, but React will drive the component logic and state management. On the back end I already have a FastAPI service in place; your task is to consume those endpoints, handle authentication with Firebase, and persist light local data through SQLite when the connection drops. The application needs to feel product-ready from day one: fast initial load, fluid charts that update live as new data streams in, and a UI that scales cleanly as we add new metrics. Efficiency and long-term maintainability matter more to me than quick hacks, so clear component structure and thoughtful API integratio...
I’m building a focused text-management feature for a new mobile app and need an experienced developer to create the storage-and-retrieval layer that will sit behind the in-app clipboard. The goal is simple: every snippet a user copies inside the app on iOS or Android should be captured, stored efficiently, and surfaced instantly when they need it again. Here is what I’m after: • Seamless interception of copied text within the app, without breaking native clipboard behaviour on either platform. • A lightweight, structured store (SQLite, Core Data, Room, or a comparable mobile-friendly database) that keeps all clipboard entries indexed by timestamp and source. • Snappy retrieval APIs that return recent items in milliseconds, with optional filtering by keyword...
Hi I want create a web application. The details are below: Adventure organizations require efficient systems to manage trekking activities involving trek organizers, staff, and participants. Currently, many trekking groups rely on spreadsheets, calls, or manual coordination, which makes it difficult to manage trek approvals, participant registrations, slot availability, and booking tracking. You are required to build a Trekking Management Application (TMA) web application that allows Admin, Trek Staff, and Users (Trekkers) to interact with the system based on their roles. Frameworks to be used These are the mandatory frameworks on which the project has to be built. Flask for API VueJS for UI VueJS Advanced with CLI (only if required, not necessary) Jinja2 templates if using CDN only fo...
Advanced OBD-II Vehicle Emulator Development (Freematics MK2 + ESP32) Develop a fully functional advanced OBD-II vehicle emulator based on the Freematics MK2 platform with any additional hardware and custom firmware/software required. The emulator must accurately simulate real vehicles across multiple OBD-II protocols and operate with commercial scan tools as though it were an actual vehicle. Required Features Support CAN, J1850 PWM, J1850 VPW, ISO 9141-2, and ISO 14230 (KWP2000) protocols. Custom firmware for complete protocol simulation and response handling. Vehicle profile library capable of storing multiple vehicle configurations. Import, save, edit, and replay complete vehicle sessions. Accurate VIN simulation (Mode 09). Calibration ID (CAL ID) simulation. Calibration Verifi...
I need a lightweight, browser-based to-do list that is built entirely with Python on the back end and plain HTML/CSS templates on the front end—no JavaScript frameworks or external languages. A minimal Flask or Django setup is fine as long as the whole stack remains Python-driven. Core requirements • Users must be able to add new tasks, edit existing ones, and mark items as completed. • No sign-up or login flow is required; the moment the page loads, the list should be ready to use. • Data can sit in an in-memory store for now (SQLite or a simple JSON file is acceptable) as long as it persists while the server is running. Please set up a clean project structure, document how to start the server in a single command, and include a brief README covering installation...
I need a complete SQL course designed for absolute beginners and I want it built around hands-on, interactive exercises rather than passive video or lengthy text. By the time a learner finishes, they should be able to write basic SELECT statements, understand simple database design concepts such as primary keys and normalization, and confidently perform INSERT, UPDATE, and DELETE operations. Scope • Structure the material in small, incremental challenges that run directly in the browser or a containerised sandbox (e.g. SQLite, MySQL or PostgreSQL—whichever you prefer as long as setup is friction-free for the learner). • Each module should introduce a concept with a brief explanation, immediately followed by an auto-graded task so students see the result of their query....

I run a single-axle truck and need a Windows-based application that brings everything I currently juggle on paper into one place. The core features I have in mind are fuel tracking, route optimization and a built-in maintenance scheduler, all updating in real time while the truck is on the road. Here is what I expect to receive: • A standalone Windows executable (installer preferred) that works on current Windows 10/11 machines. • Real-time dashboards for fuel usage, mileage and service alerts, plus a map view that recalculates best routes as traffic or fuel levels change. • A simple data store—SQLite or similar is fine—as long as I can back it up easily. • Source code, commented clearly enough that another developer could extend it later, and a bri...
