At Tech OS, each learning step is structured around a series of progressive milestones: 98 concrete project evolutions, designed as key structural checkpoints. This method ensures learning by doing, with visible impacts of technical choices at each step. The result: a precise, actionable, and controlled training, pushing for understanding rather than blind following.
And since each step is independent, impact is immediate: if some concepts are already mastered, you can jump straight to the next blocks. There's no fixed plan, just the right lever at the right time.
The 3-day format is a foundation, not a limit.
The training is designed to go far beyond, with advanced chapters ready to be activated based on the group's level. Result: even the most experienced quickly find ways to progress, without ever hitting a ceiling.

Context1-day training split into 2h/day for one person
ReviewA trainer with real-world experience, far from theory, fully focused on practical day-to-day challenges. The exchanges were highly technical and extremely relevant. One-to-one training is a real luxury. Intense, fascinating. Too short, I wish we had a full day per topic. Huge thanks to Loïc for his professional and tailored approach.
