Overview
Personal Hub is a full-stack web platform that consolidates personal productivity and career management into a single integrated dashboard. Instead of juggling multiple apps — each with its own auth, settings, and deployment — everything lives under one roof: tasks, job applications, calendar, notes, Telegram channel monitoring, and health tracking.

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 |
