Hi, I'm

Ermald
Billa

Full Stack Developer

I build fast interfaces, robust backends and the occasional hidden easter egg.

About me

Full stack developer with an obsessive passion for web performance and accessibility. When I'm not fixing production bugs at 2am, I'm building tools that make life easier.

Specialised in WordPress, Next.js and React Native. I've worked on projects ranging from WordPress themes to clinical medical applications. Every line of code is written with the end user in mind.

Passionate about web standards, open source and not to coffee. Lighthouse 100 isn't a goal, it's a standard.
