At Rok Potočnik s.p., I deliver frontend and full-stack solutions for startup and scale-up clients, building applications from the ground up with React, TypeScript, Next.js, and Vite.

At Povio, I worked across six B2B and B2C client projects and acted as Lead Frontend Engineer on two. I improved performance and developer experience, set up an iOS deployment pipeline, and mentored three junior frontend engineers.

I also built the Karate Tournament Manager from the ground up, taking ownership of frontend development, backend implementation, and data modeling in collaboration with a local karate club. Earlier at Kopa d.d., I developed a Flutter navigation app focused on accessibility and maintained a production monitoring application with real-time updates.
