02 — Behind the buildAlways a work in progress.

A curious mind.
A practical approach.
A thing for the details.

I'm Selim, a Computer Science graduate and software engineer based in Leicester. I build web applications, content platforms and tools that help people get things done.

From Java and Spring Boot to Next.js and Sanity, I care about clear architecture, accessible interfaces and software that holds up when people actually use it.
