I'm a software engineer with hands-on experience building and shipping full-stack products in fast-paced environments—from robust backend systems to the interfaces people actually use. I care deeply about writing clean, maintainable code and delivering practical, high-quality solutions.

At Iterative Financial, I worked on payment partner integrations, SDKs, backend migrations (Node.js/Express to NestJS, RabbitMQ to River), and real-time config systems—helping make our systems more reliable and productive. I enjoy building systems that balance good architecture, developer experience, and real-world reliability.
