What I'm looking for

Senior Backend Engineer

I build backend systems that stay fast under heavy traffic — sharpened over 11+ years, including 6 years keeping BookMyShow's ticketing platform stable through India's highest-traffic booking moments for millions of concurrent users.

Core stack: PHP/Laravel, MySQL, Redis, RabbitMQ. Focus: backend architecture — microservices, database optimization, and REST APIs other teams can depend on.

As Technical Lead at BeatO, I own system design through production: pricing/promotion workflows, endpoint hardening, and the code review process that keeps a team shipping clean. At Homeville Group, I optimized slow queries and integrated KYC/e-signing for regulated housing-finance platforms.

I turn legacy monoliths into modular architecture, diagnose production issues fast (Kibana, Splunk, New Relic), and lead engineers through the process, not just around it.

Open to Technical Lead / SDE-3 backend roles in fintech, high-traffic platforms, or regulated systems.
