1397 USD GemzTrade Telegram bot & WebApp
Bot DevelopmentI developed a full‑stack web application from scratch, handling both the client and server sides. For the front end, I used TypeScript, React, and Vite to create a fast, responsive interface. On the back end, I implemented a robust Python Flask server and configured PostgreSQL for efficient data management. As part of the project, I built a command‑line admin tool for managing the application and its services and developed a Telegram bot using the Python‑Telegram‑Bot library to extend existing features. This project was completed within 2 weeks.
