AI Workspace Platform

An AI workspace platform currently under development.

The architecture follows Web UI -> API (Go) -> SQS FIFO -> Worker -> PostgreSQL, decoupling heavy LLM workloads from the API layer. This keeps API latency stable while providing an asynchronous execution pipeline with FIFO ordering guarantees.

Processing flow:

  1. Request
  2. Queue
  3. Poll
  4. Save
  5. SSE Streaming (LISTEN/NOTIFY)

Database updates are pushed to the API immediately via PostgreSQL LISTEN/NOTIFY, and responses are streamed to clients in real time using SSE. The goal is to balance fault tolerance, concurrency, and real-time UX.
