Overview
Unified data and automation environment integrating task management, job-search data, Google Calendar, Google Drive, Telegram, and Garmin Connect. It combines automated data collection, cross-system workflows, dashboards, and AI-generated daily summaries. PostgreSQL connects data across modules, while scheduled integrations support recurring collection and reporting. FastAPI and Next.js provide the backend and web interface.

- Calendar — two-way Google Calendar sync with meeting notes stored locally
- Notes — Markdown editor synced with Google Drive, cross-linked to tasks and events
- Telegram Pulse — channel monitoring via MTProto with AI-generated digests (daily/weekly schedules)
- Vitals — Garmin Connect sync (steps, heart rate, sleep, exercises) with AI daily briefings
- Dashboard — centralized overview with widgets from every module
- Demo Mode — production-quality demo account with realistic data, role-based isolation at DB/API/UI levels
Technical Highlights
| Challenge | Solution |
|---|
| Multi-provider AI (OpenAI, Anthropic, Gemini) | Adapter pattern with factory; API keys encrypted with Fernet |
| Telegram channel reading | Dual approach: Telethon (MTProto) for reading + Bot API for notifications |
| Garmin rate limiting (no public API) | Circuit breaker with exponential backoff (15→120 min), sync log table |
| Demo data isolation | Three-level guard: DB query filter, API dependency, frontend flag |
| Background scheduling | APScheduler with timezone support for polling, digests, and sync jobs |
