Jan Kolenko

Senior Full Stack Engineer

Experienced software engineer with a focus on building engaging & accessible digital experiences. Proficient in database and web technologies. I build pixel-perfect, engaging, and accessible digital experiences.

Back in 2015, I decided to log "Hello World!" into console and fell into rabbit hole of coding and web development. Fast-forward to today, and I’ve had the privilege of building software for an culinary concept, a start-up, and a huge corporation.

My main focus these days is building accessible user interfaces for our dev ops at Adidas. I most enjoy building software in the sweet spot where design and engineering meet - things that look good but are also built well under the hood.

When I’m not at the computer, I enjoy catching up to software news, playing or watching sports, reading, hanging out with my friends and family, or going to gym.
