About me

I build fast, accessible web applications that reach millions of users. From the TVN24.pl news platform at Warner Bros. Discovery to insurance purchase flows at Applied Systems.

------

Over 12+ years across media, insurance, and e-commerce, I've worked on SSR architectures, microfrontend systems, design systems, and Server Driven UI. I have collaborated with international teams across Poland, the US, India, Canada, and Australia.

------

I care about real performance and shipping things that work.
