Complex ideas. Clear interfaces.

Peter Oliver Kolek

I’m Oliver, a software engineer focused on frontend development.

I design and build web applications that make complex information easier to use. From the first interaction to API integration, I turn product requirements into clear, responsive interfaces.

My work spans React, Next.js and TypeScript, with experience in backend integrations and AI applications. I care about how a product works, how it feels and how it holds up in everyday use.
