What I'm looking for

I seek backend/platform roles in fintech-focused teams where I can design scalable, reliable systems, reduce latency/costs, and work on reconciliation and payments with strong engineering and operational ownership.

I am a backend engineer with experience building high-scale fintech systems, specializing in Spring microservices, Kafka, and banking API integrations. I have driven measurable financial impact—resolving 12Cr+ discrepancies—and scaled infrastructure to support 1M+ users/month with 99.8% SLA while reducing latency by 40%.

I design reliable, cost-efficient architectures and reconciliation engines, and have delivered production features across payments, mutual funds, and trading platforms. Recognized in competitive hackathons and certified in Kafka, Spring Microservices, and Google Cloud, I focus on operational excellence and measurable outcomes.
