Overview

Ripuz explores how independent utilities and data sources can become one repeatable system. The project combines a FastAPI service, a persistent job queue, metadata processing, subprocess coordination, a browser interface, and containerized deployment.

The challenge

Coordinate tools with inconsistent output and failure behavior while keeping long-running work observable, repeatable, and safe to resume.

The approach

I separated request handling, job state, external integrations, file movement, verification, and cleanup into explicit stages backed by persistent state and tests around failure-prone boundaries.

Technical decisions

  • Use a durable job model so progress and failures remain visible across a long workflow.
  • Add preflight planning and confirmation before large batches begin.
  • Verify output before cleanup and isolate external systems behind testable adapters.

What I learned

  • Clear boundaries and explicit failure handling made the integrations easier to test and maintain.
  • Idempotency and deduplication become essential when jobs can overlap or restart.
  • Preflight checks, disk guards, and deduplication became essential parts of the workflow.
