🏗 Architecture
Workflow: 1. Flutter Mobile App → Fetches budget & transaction data from Flask API. 2. Flask API → Reads/writes data in a SQLite database. 3. Mobile App → Sends analytical questions to CrewAI API. 4. CrewAI API → Processes data & returns insights. 5. Both APIs run in Docker containers on a Raspberry Pi, accessible anywhere via Tailscale VPN.
