About

Principal Software Engineer with 9+ years of experience building and evolving high-throughput, low-latency backend platforms operating at scale. Deep expertise in systems programming, distributed architectures, and performance optimization, with a consistent track record of removing scalability bottlenecks and improving system reliability under strict latency constraints. At PubMatic, I lead and influence architectural decisions across Contextual, Identity, and Ad Serving platforms—owning critical components, driving platform migrations, and enabling sustained traffic growth for revenue-critical workloads. Known for combining strong hands-on execution with sound system design, pragmatic decision-making, and cross-team collaboration. Comfortable operating across the full lifecycle—from architecture and implementation to profiling, optimization, and long-term system evolution in production.
