About

I’m a frontend developer with more than six years of production experience. I’ve shipped for clients in the United States, Switzerland, Germany and Sweden from Prishtina. I studied maths before computer science. That’s probably why I end up on the problems that need actual thinking, and why I care so much about apps staying fast once they get big.

How I work

  • Fast once it’s big

    Proposed and shipped performance work on a US car marketplace’s listing and detail pages, and raised the performance and quality scores of Doodle’s public site.

  • In early on architecture

    Worked from early architecture discussions through to shipped features, and designed and rolled out a new URL architecture across a six-million-page catalogue.

  • Components people reuse

    Built FraktonWeb, the shared component package behind the company’s rebranded site. Teams across the organisation reused it.

  • AI in the workflow

    I follow AI tooling closely and use it in my own work.
