What I'm looking for

I seek senior roles building AI-driven, scalable web and backend systems where I can contribute end-to-end development, improve CI/CD, and drive cross-functional impact while ensuring compliance and reliability.

I am a senior software engineer with 10+ years building high-quality web, backend, and AI-driven systems, focused on delivering scalable production solutions. At Amazon, I led development of AI document-automation, chat-based assistants, voice agents, and a chart copilot that improved workflows and reduced rework.

As a founding engineer at Navan, I launched an end-to-end booking platform and built resilient backend services for bookings, expenses, payments, and policy enforcement, optimizing APIs with smart batching and vector-embedding search. I implemented automated Unit/API/E2E test suites, resilient background queues, and CI/CD with canary rollouts to enable daily deploys and high availability.

I enjoy solving complex problems, driving cross-functional collaboration, and building compliant, audit-ready systems with strong observability and automation to accelerate product delivery.
