May 2025 to Present
  • Real-Time Event Architecture: Redesigned live incident streaming from REST polling to Redis Pub/Sub WebSockets, cutting API request load by 82% (saving 1.8M calls/day) and accelerating incident propagation from 5s to <100ms across 5,000+ concurrent connections.
  • Database Optimization & Scalability: Optimized multi-tenant PostgreSQL APIs handling 10M+ rows, slashing p95 latency by 96% (4.2s to 180ms) and cutting database CPU usage from 85% to 22% by eliminating an $O(2N)$ query loop via batched Map joins and composite B-Tree indexes.
  • Low-Latency Rendering Engine: Architected a real-time computer vision validation engine in React and Canvas API, delivering sustained 60 FPS playback with 0ms visual drift across 200+ operator streams via a dual-layer requestAnimationFrame loop.
  • Client-Side Disk Caching: Engineered a client-side video disk cache in Flutter/Dio for Android (ExoPlayer) and iOS (AVPlayer), cutting seek latency by 96% (1,200ms to <45ms) and network egress by 65% by caching S3 byte-range chunks locally.
  • Distributed Session Management: Architected a distributed session reaper in Node.js and Redis, reclaiming 100% of orphaned connections and cutting server memory by 40% by synchronizing per-socket inactivity timers with 300s Redis TTLs for proactive termination.
  • Pod Leadership & CI/CD: Spearheaded an agile engineering pod of 6 to deliver OPDB V2 across 350+ retail stores with 99.9% uptime, boosting CI/CD pipeline pass rates from 68% to 94% through PgBouncer tuning and automated quality gates.
