Distributed job orchestration
A job orchestration platform: Postgres-backed queue with priorities, retries, cron schedules,
lease-based crash recovery, and a live operations UI. Jobs are claimed with
FOR UPDATE SKIP LOCKED so any number of workers can pull from the same queue
without coordination; a watchdog reclaims work lost mid-flight. Deployed continuously —
every merge ships to the live site.
Reactive bidding platform
A distributed auction platform built with Java 25, Spring Boot WebFlux, Redis, Lua, and a separate Python ML inference service for real-time fraud detection. The system focuses on atomic bid execution, low-latency state updates, asynchronous fraud scoring, and live operational visibility.
