Background

I specialise in back-end Drupal development — custom modules, complex migration scripts, and adapting to whatever structure a client's site demands. Currently a Drupal Developer at newcity, where colleagues know me as the team's go-to for Drupal solutions.

My background spans PHP frameworks, CMS platforms, and everything the open web has thrown at me over 19 years — starting with an HTML site I built after high school and growing into a career defined by technical versatility. I regularly pick up new technologies and frameworks to solve client-specific challenges.

My favourite part of the job is solving difficult coding problems and writing migrations. "The more difficult they are, the more satisfaction I have once they are solved."

Outside of code: speedway racing, NBA games, travelling, and an ongoing attempt to learn Italian. Based in Bydgoszcz, Poland.
