A little about me
I enjoy working across the entire product journey — understanding a problem, shaping an interface, designing the architecture and turning it into something people can actually use.
My work spans web, backend and mobile development, with a particular interest in minimal interfaces, developer experience and thoughtful product design.

Beyond the code
I'm a software developer who enjoys understanding how things work and turning that understanding into useful software.
I care about interfaces, architecture and the small details that make a product feel finished.
When I'm not working on a product, I like building experiments simply because I want to know if I can.
Complex problems don't always need complicated interfaces.
The fastest way to understand an idea is often to build it.
Small interactions can completely change how software feels.
Have an idea?
I'm always interested in interesting products, technical challenges and collaborations.
