I'm Michaël Mazurczak.
I live in Lyon, France, where I help individuals and startups build secure and resilient software.
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, it allowed me to discover new ways to run companies and to experiment with a lot of different projects and teams. I started with Ruby on Rails and at the end of my first freelancing experience I mainly contracted for NodeJS and React projects as a fullstack developer.
After 5 years helping scale-ups hire, structure their teams and manage legacy code, I'm ready to start freelancing again with a wealth of experience and a passion for building great products.
