What I'm looking for

I seek senior engineering roles building scalable, reliable systems at product-driven companies where I can lead architecture, improve developer productivity, and drive measurable performance gains.

I am a Senior Software Engineer with 14+ years of experience building scalable, production-ready systems at Meta and Amazon, focused on backend development, distributed systems, and service-oriented architectures. I deliver reliable web services and full-stack solutions that serve millions of daily active users, emphasizing performance, scalability, and maintainability.

I have led end-to-end initiatives including monorepo architectures, event-driven workflows, and comprehensive CI/CD/testing pipelines, improving developer productivity and reducing defects. I collaborate cross-functionally to drive architectural decisions and operational excellence, with proven impact in latency reduction, resiliency, and feature delivery at scale.
