I’m a software developer based in London. I like understanding how people work, then building tools that make their day a little easier.
Currently, I contribute to GSD London’s internal platform and build Munhae Studio, a desktop workspace for Classical Chinese translation. I also maintain Estait, a product used by real estate agencies in Seoul.
My projects have taken me from Android to browser extensions, desktop apps, and web platforms. I enjoy connecting the interface, the data, and the details that keep a product useful after launch.
Mostly working with TypeScript, React, Next.js, Electron, Python, and PostgreSQL.
