Summary
🤩
RockstarKarthik Ramgopal is a Distinguished Engineer based in Atherton, CA with ten years of experience leading product engineering at LinkedIn, acting as the technical lead and architect for high-impact initiatives including gRPC migration, infrastructure-driven client-side tracking, and the LinkedIn Generative AI copilot. He is a full‑stack leader who has driven large platform migrations from JSON to Protocol Buffers, GraphQL adoption and product features such as Events, video sharing and live audio, while balancing product velocity with operability. As a contributor to the popular Rest.li framework, he has optimized Protobuf parsing, reduced GC pressure and improved robustness around surrogate pairs — practical performance work that benefits a widely used service framework. His earlier career spans enterprise mobile security at MaaS360 and low-latency trading systems at D. E. Shaw, giving him a rare combination of systems, security and performance expertise.
