Full-stack developer focused on backend engineering
Building reliable systems and purposeful experiences for the web.
I am a full-stack developer focused on backend engineering with Java and Spring Boot. I am building a deeper understanding of APIs, databases, distributed systems and software architecture while using Next.js, React and TypeScript to deliver complete web products.
I care about systems that are reliable, maintainable and designed with a clear purpose — from the business rules and data flow to the interface used by the final user.
