About

I'm a software engineer at AWS, contributing to open-source projects including the Amplify Flutter SDK and AWS Blocks. I work across mobile and cloud technologies, primarily with Flutter, TypeScript, and Node.js.

My background includes embedded systems and electronics, which I studied as a minor. I enjoy contributing to open-source software and exploring different areas of development.
