Work history
Full-Stack Developer — “Jumanji” Platform
Freelance / Personal Project
Jan 2024 – Dec 2024
• Developed a fully functional web platform for ordering food and drinks with client, operator, and administrative sections.
• Front-end: built on React + TypeScript + Redux, using Next-like routing architecture.
• Back-end: implemented on Node.js (Express + TypeScript) with Prisma ORM for interacting with the MySQL database, including schemas for users, orders, and menu items.
• Developed a REST API with JWT authorisation and a role system (‘client’, “operator”, ‘admin’).
• Optimised query logic and database structure for faster order processing.
• Integrated a Telegram bot (Node.js + Telegraf) to notify operators of new orders and update statuses in real time.
• Used Git/GitHub for version control and maintaining separate repositories:
JumanjiFront — client side
JumanjiBeck — server logic and API
JumanjiBOT — Telegram bot for operators
• Ensured consistent architecture and code structure across all system components.
