What I'm looking for

I'm looking to build and improve low-latency distributed backend systems, with opportunities to own reliability, performance optimization, incident response, and technical leadership.

At SBI Securities, I lead microservices redesign for 500K+ daily trades, cutting response time from 150ms to 90ms while sustaining 99.95% uptime.

I optimize high-volume systems to 50K RPS and 10ms p99 latency through B-Tree indexing, read replicas, load balancing, circuit breakers, and adaptive timeouts. My work reduced cascading failures by 83% and prevented an estimated $2.1M in annual downtime.

Previously at Market Simplified, I engineered REST APIs for 50K+ concurrent users and built distributed systems using lock-free data structures. I improved latency, caching efficiency, query throughput, deployment autonomy, and defect rates across services.

I also bring Linux device-driver performance work from ADLINK Technology and testing experience from Valeo. I enjoy strengthening reliability through observability, automated testing, incident response, and mentoring engineers.
