Welcome I'm Tomas Pustelnik

I'm front-end developer with focus on semantic HTML, CSS, performance and accessibility. Author of few small open-source projects and founder of Clipio — a web clipping tool for Notion. Currently helping build React at Ataccama. Fan of great and clever design, tooling addict and neverending learner.

I write irregularry about front-end development and about my founder's journey.
