"Harmony of Mind"

Project was taken over at an early stage of implementation and required structural refinement. The task was to implement a Telegram bot in Python with a subscription model for access to psychological exercises within the bot.

A Telegram bot with the following functionality:

• Navigation through exercise sections (breathing, cognitive, emotional)
• Content creation via Markdown with media support
• 3-level access system: administrator, full, free
• Loading a mini-app with breathing exercises, full-screen mode
• Access purchase via YooKassa (secure webhooks, idempotency)
• User profile displaying subscription status
• Admin panel for viewing users, their subscriptions, granting and revoking admin rights
• Message broadcasting to users with FSM and media support

I gained experience working with:

• Claude 3.7 Sonnet AI model in Cursor IDE
• Python programming language (asynchronous approach)
• Telegram Bot API (FSM, Middleware, Webhook), Mini-app debugging
• YooKassa API for payments
• Local file DBMS SQLite (aiosqlite)
• Database migrations using Alembic
• SQLAlchemy ORM for data access (Repository pattern)
• Vite local development server
• VPS on Ubuntu Server with aaPanel
• Production environment setup (Nginx, Gunicorn, Systemd)
