I have prepared a concise technical exercise that covers the complete workflow of a modern web application, from database layer to browser. The specification document is already written and will be shared immediately after we start; please follow it exactly and return a fully working solution. Scope • The assignment is strictly full-stack, so plan to wire up everything end-to-end. • Frontend must be built with React. Feel free to enrich it with hooks, TypeScript, Redux Toolkit or any other React-friendly utilities you prefer, as long as setup and usage are clear. • Backend must run on Node.js. You may structure it with Express, NestJS or a lightweight custom framework; again, keep dependencies reasonable and document any architectural decisions. • Persist data ...

I’m looking for a developer who can create a Windows-based desktop application that will run day-to-day operations for a busy gym. The core build must combine four areas in one smooth, intuitive interface: • Biometric attendance – integrate a fingerprint scanner so members check in instantly at reception and each visit is time-stamped in the database. • Members management – store and edit personal details (name, age, contact info) and keep a full membership history, including join date, renewals and plan changes. • Billing – generate branded invoices automatically, track every payment against the correct member record, flag overdue accounts and show real-time revenue dashboards. • Reporting – export attendance logs, membership statis...
I need a straightforward Android application that lets a user record daily expenses and keep an eye on their spending habits over time. Core workflow is simple: the user adds an expense, assigns one of five fixed categories (Food, Transport, Shopping, Bills, Other), and can later update or remove that record whenever needed. Every entry is stored locally with Room/SQLite so everything works offline. The interface can stick with the default Android UI components; polished visuals are welcome, but I do not require a full-blown Material makeover. What matters is a clean layout, dark-mode support, and snappy navigation between the main screens: • Dashboard – an overview that totals weekly and monthly spend, plus a running balance. • Detail list – searchable and filter...

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.

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...
