Hi, I'm Dimitri.

I create and gather programming exercises for beginners and intermediate learners. I focus on bite-sized exercises, tailored for random and regular practice: no storytelling, no riddle, minimal use of math (basic arithmetic).

These exercises are for you if you want to become a proficient JavaScript web developer, either as a freelance or in a small or medium-sized company.
