Designed and implemented a distributed queue architecture using PGMQ integrated with Supabase PostgREST, processing 10,000+ messages daily. Reduced system message load from 18,000 to 10,000 while maintaining the same user experience by consolidating redundant queue operations and implementing intelligent batching. Eliminated loading bottlenecks through asynchronous queue-based workflows. Built a dynamic observability system with structured logging and real-time metrics via Hotjar and Vercel Analytics. Resolved high memory consumption with request deduplication and caching strategies.
