A picture of me at 33 years old, smiling to the camera

Hi! I'm Julien, but the internet knows me as @tiesselune.

About me

I’m a 33 years old french freelance software engineer, doubling down as a computer science teacher.

I have worked in the video game industry as an engine and gameplay developer, as well as a systems and web developer on various unrelated and related projects. (Did you know most indie game developers do not earn a living from their games alone ?! 😱 Flabbergasting, I know.)

I have also taught web, systems and game programming in several private schools in France, and online, in the meantime.

I started coding when I was 14 and never stopped, always finding an occasion to play with the next shiny thing ✨ out of sheer curiosity.
