> about
I'm Michaël Mazurczak. I build secure, resilient software from Lyon, France.
I love to understand the world we live in, and as such I love discovering new concepts and tinkering with them. Computers were a means to explore new ways to communicate and create.
My first job was as a cinema operator, from there I maintained the cinema's website and wrote little scripts to help me in my daily tasks. I wanted to create a digital music label and gained core technical skills in the meantime.
I went freelance for 10 years. Started with Ruby on Rails, ended up building with React, Node.js, Elixir, and Rust. Along the way I worked with scale-ups, helped structure teams, managed legacy code, and shipped a lot of product.
Now I'm building my own products while helping others do the same.
