About

I'm Maciek Korsan, a senior software engineer from Białystok, building for the web since 2005. I've been a senior and lead frontend developer, then product manager and senior engineer at Syncano / Eyedea. Since 2021 I've worked at Arkency as a senior engineer on Rails products with Hotwire and Tailwind CSS. I co-organise the Programistok conference and sit on the 4Developers programme council. On stage I talk about frontend craft and about code that makes music.
