I build reliable networking features, high-performance microservices, and systems software.

At Cisco, I develop NX-OS networking features for enterprise switches, including TCP keepalive support for syslogd and Kstack support for Callhome and Smart Licensing. I also migrated a private curl implementation to FOSS curl by resolving complex linker-preloading dependencies.

Previously at Hero MotoCorp, I maintained consumer-facing microservices and built RESTful APIs for notifications and trip history. I optimized the Feature Management API from 8 seconds to 0.5 seconds, making it 16 times faster.

My M.Tech. work at IIT Madras focused on implementing a RISC-V vector extension for the SHAKTI C Class processor, optimizing SIMD operations, memory access patterns, and data movement.
