About me

I'm passionate about design system architecture and building reusable, accessible UI components that scale across teams. I focus on standardising front-end patterns while maintaining system consistency and performance optimisation in production environments.

In my free time, I mentor students through the Bosnia and Herzegovina Futures Foundation, helping the next generation of developers build their careers in technology.
