About

Backend and systems software engineer at Zscaler, where I build high-performance, high-scale microservices that power global DNS and traffic routing for millions of users. I work close to — CC++ & Jave on Linux — so process management, memory, concurrency, and networking are where I live day to day. - Design and own backend services end to end: architecture, implementation, testing, deployment, and production reliability. - Build for scale and low latency: concurrent Go services, C performance optimization, Redis-backed data paths, and clean, testable code. - Operate in production: Linux debugging, observability, Kubernetes/Docker, and incident response with a reproduce → isolate → instrument → fix → prevent mindset. - Own Go microservices for geo-aware DNS policy and VIP/traffic routing, including Redis sorted-set ranking and multi-domain routing, backed by thorough unit test coverage. - Refactored a production networking module into a reusable library — improving build reliability and cross-team reuse with zero behavior change. - Drove latency improvements in traffic routing through low-level C and memory optimization. Tech I use: Go, C, Python, Linux, Kubernetes, Docker, Redis, MySQL, REST APIs, CI/CD, Git, observability (structured logging, metrics, tracing), Claude code. I care about ownership, clean systems, and measurable impact. Open to backend, distributed systems, systems/networking, and cloud/container security roles.
