About Me

Passionate about creating exceptional digital experiences

Dalibor Králik

My Journey

With over 4 years of experience in modern front-end development, I've successfully delivered projects for universities, Fortune 500 companies, and innovative startups across Central Europe. My passion lies in creating interfaces that are not just visually appealing, but also highly functional, accessible, and performant.

Based in Slovakia and Czech Republic, I specialize in React, Next.js, and TypeScript, delivering high-performance applications that scale. When I'm not coding, you can find me improving my knowledge in project management, team management, and leadership. I'm also interested in Web3 and AI technologies.

What I Focus On

  • Integration of the AI into the development workflow
  • Performance optimization and front-end testing
  • Accessible and inclusive design
  • Modern React patterns and TypeScript
  • Smooth animations and micro-interactions
