What I'm looking for

I seek roles building scalable, data-driven backend and platform systems with strong observability, reliability, and cross-functional collaboration.

I am a Senior Software Engineer with 10+ years building scalable, reliable systems that drive measurable business impact. I have led ad-ranking and pricing initiatives at Google that contributed to multimillion-dollar ARR and built secure, real-time telemedicine infrastructure at GE Healthcare integrating clinical systems and enabling virtual collaboration.

My craft sits at the intersection of data, architecture, and product experience: I design backend services in Java and Python for high-QPS environments, refactor legacy systems into service-oriented architectures using gRPC and containers, and partner with ML and data science to productionize inference pipelines. I emphasize observability, testing, and mentorship to reduce MTTR and improve release quality.
