What I'm looking for

I am seeking roles building scalable backend or network systems where I can design robust architectures, mentor engineers, and drive measurable reliability improvements.

I am a senior software engineer with strong expertise in C++ network systems, backend service architecture, and distributed systems. I have led global expansions of services and built robust network-recovery features that improved reliability for users at scale.

At Amazon, I architected and led the global rollout of the Seller Referral Service, created a configuration-driven framework for international requirements, and improved seller automation workflows that increased adoption and cut processing time.

Previously, I implemented network re-establishment modules and travel-resilient connectivity features at Fujitsu Research, reducing dropped calls and ensuring uninterrupted user connectivity. I have a history of resolving critical issues, including memory leaks and latency problems, using tools like Valgrind and Klocwork.

I hold a B.Tech in Mathematics and Computing and have built projects such as a multithreaded TCP/IP server and a libpcap-based packet sniffer. I focus on scalable design, mentor junior engineers, and produce clear technical documentation to enable maintainability and future growth.
