What I'm looking for

I seek senior engineering roles where I can design scalable backend systems, improve payments and automation, mentor teams, and deliver secure, production-grade software in collaborative, impactful environments.

I am a Senior Software Engineer with 11+ years building high-quality web, backend, and AI-driven systems, focused on scalable, reliable, and user-centered solutions.

At Amazon I developed backend services for a healthcare platform—patient intake, billing, scheduling, video visits—and led payments, background jobs, automation, and monitoring to improve reliability and reduce incidents. Previously at Teladoc Health I built telemedicine backends, automated patient workflows, and implemented end-to-end payments and conversational automation that significantly reduced manual work.

I excel at designing modular, testable systems (payments SDKs, pluggable gateway layers), driving automation, and collaborating with cross-functional teams to deliver secure, compliant, and production-grade services.
