We already have a working backend that parses betting data in real time and pushes it into PostgreSQL via a Fastify.js API. The parsing and data ingestion part is already done and production-ready
Now we need to extend the backend with business logic and Telеgram bot integration.
What needs to be done:
User & subscription management: * Implement logic to check if a user has an active paid subscription (via webhook + periodic polling). * Create tables for `users` and `user_filters` in PostgreSQL. * Add ability to grant subscriptions for N days from an admin account inside Telеgram bot.
User filters via Telеgram bot (grammY framework) * Users should be able to configure filters (sports, odds, etc.) directly through the bot. * Filters should update in PostgreSQL in real time.
Notification system: * When a new bet arrives (already parsed & stored), check user filters. * If the bet matches a user’s filters and subscription is active, send notification via Telеgram bot.
Queue implementation: * Integrate BullMQ for handling Telеgram rate limits. * Ensure message delivery to users without hitting Telеgram flood limits.
Deliverables: * PostgreSQL migrations for users & filters * Working Telеgram bot (grammY) with subscription check + filter management * BullMQ queue integrated for rate-safe notifications * Backend & bot code configured to run as PM2 processes on Ubuntu VPS * Clean, maintainable Node.js/Fastify code
Notes: * Parsing & API already implemented — focus is only on business logic, subscriptions, bot, and queue. * Example code available. * Rapid development style: OK to use Cursor AI (I can provide credits). * Estimated workload: ~1 day.
