Overview We are looking for a user-interface tester with the initiative to take a written brief describing how a feature is intended to behave and independently turn it into their own test plan — identifying the scenarios, edge cases, and checks that confirm the application works as it should. This is a functional, interface-focused role. You will succeed here on the strength of your testing instincts and attention to detail. No coding, database, or technical development background is required. What matters is how you think: when you read a feature description, we want your first instinct to be "here are the ways this could behave unexpectedly, and here is how I would confirm each one." Briefs will be provided to you from two sources: written specifications we prepare, a...

I need a custom-built inventory management application that runs natively on Windows desktops. The core focus is robust reporting and analytics paired with an intuitive supplier-management module, so I can monitor purchasing patterns, lead times, and cost trends in a few clicks. Here are the essentials I’m expecting: • A clean, responsive Windows UI (WPF, WinForms, Electron—use what you’re strongest in) connected to a solid database layer. • Reporting & analytics dashboards that let me slice stock data by SKU, date range, location, and supplier, with export to Excel/PDF. • A supplier management section where I can store contacts, terms, past orders, and automatically flag preferred vendors. • Straightforward install package or one-click upd...
The public-facing web app I’m about to launch needs a final, end-to-end quality sweep. I want both manual exploratory passes and an automated regression suite so every critical pathway is covered across the two primary browsers my users rely on—Chrome and Safari. Manual work should dig into usability, edge-case behaviour, and visual consistency, surfacing clear, reproducible bug reports with screenshots or screen-captures. In parallel, I expect a maintainable set of automated tests (Selenium, Cypress, Playwright or a similar framework you’re comfortable with) that I can plug into my CI pipeline for continual coverage after hand-off. Deliverables • Detailed test plan outlining scope, assumptions, and acceptance criteria • Structured bug/issue reports with s...
We're preparing to launch a full Electronic Medical Records (EMR) platform that ties together three layers: our patient-acquisition / marketing side, the physician back office, and the live clinical workspace used during doctor–patient consultations. Before go-live, we need an experienced QA specialist to validate the entire application in a staging environment mirroring production. Scope Functional testing across all core modules marketing, physician back office, clinical workspace, and each layer's admin panel. UI/UX verification so every screen, control, and flow matches the design spec and behaves consistently. Data-level validation to confirm patient records, billing, and marketing metrics stay accurate end to end. Load and stress testing to surface bottlenecks under ...
I need a small program that quietly runs on our server and keeps the freight information on our public site completely in-sync with a local source folder. Every ten minutes it should: • scan the designated directory, • upload any new or changed text files, • remove any text files that were deleted from the directory, so the web content always mirrors what we have internally. The directory path will be configurable; everything in that folder is considered authoritative. Reliability and low overhead are far more important than fancy visuals, so feel free to use a lightweight approach—Python with watchdog and an FTP/SFTP library, a PHP cron job, a Node script, or another solution you prefer—as long as it can run unattended on a typical Linux hosting environ...
I’m building the low-level firmware for an ARM Cortex-A microcontroller and need help closing the remaining gaps in startup code, peripheral configuration, and board-level testing. The toolchain is already in place (GCC, OpenOCD, and a J-Link probe), and the hardware boots, but several peripherals still need clean, maintainable drivers and the overall initialization sequence must be tightened for reliable production use. You’ll dive into: • Writing or refactoring C/C++ startup routines, linker scripts, and BSP code specific to this Cortex-A device • Bringing up UART, SPI, GPIO, and a high-speed interface that feeds data to an upstream processor • Tracing hard faults with JTAG/SWD and delivering concise root-cause notes so I can reproduce your findings &bul...
I already have a fully working handicapping routine for horse racing that I pieced together with Copilot, plus an older sample application that shows the exact flow and screens I want. What’s missing is a clean Windows-ready .exe so I can run the program (and share it with a few friends) without installing a full development environment. Here’s the current state: • All source files are ready to hand over, neatly commented. • Copilot can regenerate any individual factor or module on demand, so if you prefer rebuilding specific parts, that’s available. • I’m still deciding between a lightweight command-line tool and a simple GUI; I’d welcome your advice on which will compile most reliably and be easiest to maintain. Your role: 1. Review the exis...
I need an experienced hand with Microsoft SQL Server who can both build and scrutinise. On the development side you will design the underlying database for a desktop application, write and fine-tune the T-SQL queries it relies on, and wrap key logic into clear, reusable stored procedures. Once the data layer is in place I want a second set of eyes on the finished product: structured manual testing of the desktop app, covering common user flows as well as edge cases that could expose performance or integrity issues. Precise reproduction steps, screenshots or short clips, and concise bug reports in a tracker of our choice will be expected for anything you uncover. Deliverables • Normalised schema and migration scripts • Optimised queries and documented stored procedures ...
My application is ready for a dedicated round of performance validation and I need a specialist who can concentrate exclusively on load testing. The aim is to simulate realistic user traffic, capture solid data on response time and throughput, and translate that data into clear, actionable recommendations for tuning the system. You are free to work with the tool-set you know best—Apache JMeter, Gatling, LoadRunner, or any similar platform—as long as the results are repeatable and easy for my team to verify later. We can iterate together on scenario design, but I expect guidance on industry-standard workloads and step-up patterns so the numbers we collect truly reflect production behaviour. Deliverables • Load-test plan outlining scenarios, user counts, and ramp-up stra...
My five-person consulting firm needs a dependable partner who can handle our day-to-day IT environment entirely off-site. While we will continue to lean on you for onboarding and security matters, the area that will make or break this relationship is ongoing IT support; keeping us up and running without hiccups is the priority. Here is what the engagement looks like from my side: • On an average month you will perform regular system maintenance, jump in quickly to troubleshoot anything that crops up, tune performance so laptops stay snappy, and spin up new machines or cloud user profiles whenever we add a team member. • Remote desktop tools, monitoring and management software, and solid security software should already be in your toolkit so you can diagnose issues, patch syst...
I need a MATLAB-based GUI that runs on Windows and turns data workflows into a clean point-and-click experience. The application’s core goals are simple: let users bring data in, explore it interactively, and keep their project files organised in one place. Functionality • Data input and display – accept common formats (CSV, MAT, TXT) and show tables or plots instantly. • Interactive graphics – zoom, pan, cursors, and basic annotation so users can interrogate their data visually. • File management – open, save, create new sessions, and overwrite files safely from within the interface. Technical notes – MATLAB on Windows is the target environment; code written in App Designer or programmatic UIFigure is fine so long as it installs and l...

My hardware-material e-commerce mobile app is approaching its launch window and I need a fresh, systematic review of every shopper action. The focus is pure functionality: cart behaviour, checkout flow, search accuracy, stock/price updates, coupon handling, push-notification triggers—the whole path from install to confirmed order must feel bullet-proof. The build is available on TestFlight and a closed Android track, so please install on both iOS and Android phones and tablets to surface any platform-specific quirks. I will share credentials, seed data and a list of edge-case scenarios (e.g., combining multiple discount codes, rapid quantity edits, flaky network) once we start. Deliverables • A concise test plan outlining device/OS coverage and the scenarios you executed &...
I have taken an electric-vehicle concept through its preliminary design stages and now want to validate the motor and drivetrain. My main focus is comprehensive performance testing—electrical, mechanical, and software/control—to verify that the hardware and embedded logic meet the predicted specs before we proceed to pilot production. Scope You will plan and execute a coordinated test campaign on the assembled power-unit (inverter, motor, reduction gear, and associated control firmware). Real-time data acquisition, repeatable procedures, and clear reporting are crucial. Key test areas • Electrical performance testing • Mechanical performance testing • Software / control-system testing Typical tools you might draw on include dynamometers, oscilloscope...
I’ve built a macOS utility and already pushed it to TestFlight, but before the final App Store review I need an experienced tester’s eye. Apple has asked for a screen-recorded session that demonstrates the app in action, and I also want to be absolutely sure it complies with every guideline. Here’s what I need from you: • Install the TestFlight build on at least one Mac running the latest macOS release and another on an older supported version. • Exercise every user-facing area, paying close attention to interface interactions, core functionality and overall performance. • Capture a high-quality screen recording of the full test run, showing onboarding, feature use, and a clean quit. • Provide a concise report outlining any crashes, UI glitches...
My N8N-based virtual agent is throwing workflow errors. The problem surfaces in the middleware logic and manifests as the trigger firing multiple times when it should execute only once per event. I need the root cause identified, the flow corrected, and a brief explanation of what was changed so I can maintain it going forward. You’ll have access to the current .json export and, if helpful, a short Loom walkthrough that shows the mis-behaviour in real time. Please use the built-in N8N debugger and any Node.js or TypeScript tools you find convenient—just keep the final solution confined to the N8N environment so I can import it back without extra dependencies. Deliverables: • Cleaned-up workflow file(s) with the middleware logic fixed • Confirmation that the trigge...
I’m ready to release the next version of my Windows-based desktop application and need a developer who can take the current build, incorporate the planned feature updates, and package a clean, fully-tested installer. You’ll receive the existing source code, UI mock-ups for the new screens, and a concise change log outlining bug fixes and enhancements. Key goals • Refactor and extend the present code so the new functionality feels native, not bolted on. • Maintain compatibility with Windows 10 and 11. • Produce an installer that supports silent and standard setups. Once you have everything running smoothly on a staging machine, I’d like a brief hand-off session covering what changed, how to compile, and how to push future hotfixes. If you have so...

I have an existing Python-based program built on an established automotive industry framework, and I need to turn its current manual verification and validation steps into a fully automated process. The focus is squarely on software testing: the goal is to generate a clean, well-structured script (or set of scripts) that can exercise the application under realistic conditions, log results, and flag regressions without human intervention. During a short call I will walk you through the codebase, the framework dependencies, and the exact pass/fail criteria we already use in production. From there, you will design and implement the automation logic in Python, wiring it into our CI environment (Git, pytest, or an equivalent runner—whichever you are most comfortable with). Clear, well-co...

I need a complete, AnyDesk-like application built specifically for Windows. The core scope is clear: • Remote control: smooth, low-latency screen sharing with mouse-keyboard input redirection. • File transfer: drag-and-drop or dialog-based, both directions, showing progress. • Session recording: full-quality capture saved locally on the host machine. Only simple user authentication is required—think a one-time password or PIN exchanged between peers before a session begins. No granular role management is needed at this stage, but the code should make it easy to extend later. I will judge the delivery on these acceptance criteria: 1. A Windows-ready installer and an easily runnable portable build. 2. Source code with clear comments, building cleanly from scra...

DESARROLLO DE APP MOVIL DE TRANSPORTE COLECTIVO CON RUTAS FIJAS Y RESERVA DE ASIENTOS (iOS + ANDROID + PANEL WEB) RESUMEN DEL PROYECTO Busco desarrollar una aplicacion movil de transporte colectivo (tipo Uber, pero con rutas fijas y reserva de asientos, similar a un sistema de shuttle/bus con seguimiento en vivo), disponible en iOS y Android, con diseño minimalista y flujo de uso limpio. Importante: NO es un clon de Uber tradicional. Los vehiculos (autos/combis de 4 a 14 asientos) operan en rutas predefinidas (ej. San Isidro - Chosica, en Lima, Peru) con paraderos establecidos. El pasajero no pide un viaje a cualquier destino: elige la ruta, ve los conductores activos, selecciona su asiento en un mapa del vehiculo y paga su cupo. El vehiculo parte cuando se llena o cuando el cond...
