Bridging complex systems and intuitive design.

I’m a Full Stack Software Engineer at Songtrust, crafting performant user experiences backed by robust architecture using TypeScript, React, GraphQL, Python, Django, and AWS.

Most recently, I built MangoWave, an open-source audio visualizer.

Previously, I was a Doctor of Physical Therapy. That background shaped my "diagnostic" approach to engineering: I don't just treat symptoms; I dig for root causes to build software that is healthy, maintainable, and solves real user problems.

Let's Connect

I’m currently building full-stack features at Songtrust and shipping open-source projects like MangoWave.

I’m always open to connecting. Feel free to reach out if you want to nerd out about software architecture, video games, lifting, or the transition from healthcare to engineering.
