What I'm looking for

I seek a technical leadership role building scalable, serverless systems and AI-driven platforms with strong engineering practices, mentorship opportunities, and measurable product impact.

I am a senior backend engineer with deep experience architecting scalable serverless and microservice systems on AWS, building authentication, payment and notification platforms, and integrating AI-powered search. I focus on measurable impact—reducing latency, improving match precision, and increasing deployment velocity.

I have led founding-engineer efforts, designed high-throughput data pipelines, and implemented robust RBAC, CI/CD and observability practices used across production services. My work has supported large user bases and high daily transaction volumes while improving security and cost efficiency.

I mentor engineering teams, drive hiring and onboarding processes, and standardize engineering best practices to scale organizations. I seek to deliver pragmatic technical leadership that aligns product goals with operational excellence.
