About
Engineering beyond the interface.
I’m a Senior Software Engineer who builds dependable digital products across web, mobile, backend, and cloud. I take ownership from product discovery and system architecture through customer and admin experiences, APIs, data models, infrastructure, automated delivery, and production operations. My strength is connecting every layer of a product—turning complex requirements into scalable systems with thoughtful UX, reliable real-time workflows, secure payments, notifications, and maintainable engineering foundations.
