About

My path into software wasn't a straight line — and that's exactly what I bring to every project.

With an undergraduate background in Biology from UC Davis and a Master's in Computer Science from Northeastern University, I've trained myself to think across disciplines: to question systems, find root causes, and design solutions that hold up under pressure.

One required programming course was enough to redirect my entire career. Since then I've built full-stack web platforms using the MERN stack, earned a Professional Certificate in Machine Learning & AI from UC Berkeley, and achieved AWS Certified Solutions Architect – Associate status to deepen my cloud expertise.

I work best at the intersection of technical depth and clear communication — whether that's designing RESTful APIs, prototyping UIs in Figma, or shipping a responsive product end-to-end.
