PROJECTS
Monobot - Automated Expense Tracking
Go · Monobank API · Telegram Bot API · SQLite · Google Sheets API · Docker · Railway · robfig/cron
Telegram bot for automatic personal finance tracking. It polls the Monobank API every 5 minutes, retrieves new transactions, and categorizes them using a keyword dictionary. If a transaction is unknown, it sends a message with inline buttons so the user can choose the category manually; the system then remembers the pattern. Processed data is stored in SQLite and exported to Google Sheets for visualization. The bot runs 24/7 on Railway.
• HTTP client for the Monobank API with timeouts and error handling
• Two-level classification: dictionary -> manual labeling with learning
• Asynchronous Telegram update loop with thread-safe handlers using sync.Mutex
• Transaction deduplication with INSERT OR IGNORE and resilience to restarts
• Cron scheduler for regular API polling
• Multi-stage Docker build and Railway deployment with a persistent Volume for SQLite
