What I'm looking for

I seek roles building large-scale, production AI/platform systems where I can lead cross-functional engineering, improve observability and performance, and ship end-to-end features in cloud-native environments.

I am a Senior Software Engineer with 10 years of full-stack and platform engineering experience across Databricks, Facebook, and Epic, focused on building scalable systems, AI-driven products, and real-time collaboration features. I led key components of Databricks Assistant—serving 150K+ MAU and delivering 72% productivity gains—designed metrics/logging microservices, built real-time sync engines with CRDTs, and optimized language runtimes for major performance and cost improvements.

I collaborate cross-functionally to integrate MLflow, Delta Lake, and Spark into production workflows, and I ship end-to-end features across backend and frontend stacks using Go, Java, Python, React, and TypeScript. I prioritize reliability, observability, and developer velocity, and bring proven experience in event-driven architectures, model serving, and cloud-native deployments on AWS and Azure.
