What I'm looking for

I seek senior engineering roles owning backend and AI-driven systems, improving reliability and payments, leading end-to-end development, mentoring teams, and working in security- and compliance-focused, cross-functional environments.

I am a Senior Software Engineer with 11+ years building and delivering high-quality web, backend, and AI-driven systems for large-scale healthcare and payments platforms. At Amazon I owned services for patient intake, billing, scheduling, and video visits and built an Amazon Pay SDK that made payments modular, reliable, and easy to integrate.

I specialize in end-to-end development—from architecture and payments to automation, testing, and live monitoring—and I prioritize scalability, security, and compliance. I enjoy reducing manual work through automation, mentoring teams, and collaborating across functions to ship reliable, user-focused products.
