<hello />

I am Fai

Full-Stack Engineer

I design and build web and mobile products across the full stack, from user-facing experiences to backend systems and architecture. My recent work spans healthcare platforms, AI-enabled applications, and production software used in real-world environments.

About Me

I’m naturally curious about how things work and how they can be made better. That curiosity shapes how I approach software: understand the problem, explore different ideas, and turn them into something useful.

I care about both how a product works and how it feels to use, with design influencing how I think about interfaces, workflows, and the details that make software feel intuitive.

My Process

Most things I build start a little messy: a problem, a scrapbook of ideas, and a lot of questions. Then comes research, experimentation, building, breaking things, and refining until it works.

Outside the Code

Outside of software, writing and music are important creative outlets for me. I write through Apjot and also enjoy songwriting.

I’m also a football fan and enjoy playing whenever I get the chance.
