Android streaming app.

A streaming app with its own API, worker queue, and self-hosted delivery, from the Kotlin client to the Caddy edge it is served through.

Stack: Kotlin, FastAPI, Postgres, Redis, Docker
Scale: Self-hosted end to end
Role: Solo

How it works

The Android client talks to a FastAPI backend. Long-running jobs go onto a Redis-backed queue and are handled by workers and a scheduler, all as Docker services on one VPS.

Caddy terminates TLS and serves the app's download endpoint alongside the API, with certificates renewed automatically.

Hard parts

Keeping a one-machine deployment reliable: health checks, restarts, and backups without a platform team.

Outcome

A complete product, client to edge, that runs unattended.
