I build full-stack applications with clean interfaces, reliable APIs, and practical architecture.

I’m Mason Dubelbeis, a software engineer focused on full-stack development with Typescript, React, Node.js, Express, APIs, databases, and practical deployment-ready architecture. I also bring a strong Java/Spring Boot foundation, which shaped the way I design secure APIs, relational data models, and production-style backend systems.

My background in Navy leadership and enterprise IT shaped the way I build: with ownership, structure, troubleshooting discipline, and a focus on software that creates real operational value.
