"I'm most proud of building our real-time notification system from scratch. The challenge was delivering millions of notifications with sub-second latency. I designed a pub/sub architecture with Redis, implemented graceful degradation, and created a monitoring dashboard. We achieved 99.9% delivery rate with 200ms p99 latency. Seeing users engage more because of timely notifications was incredibly rewarding."
