About me

I’m a software engineer with a computer science background who enjoys building real products.

I build web and mobile applications, working across frontend and backend. I spend most of my time on the frontend building clean systems, and I also build backend APIs and work with data to make sure everything works smoothly end to end.

I care about writing simple, readable code and building things that are easy to use and maintain.
