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.
ContextComplete 3-day training
ReviewI come from a Java backend background and I clearly saw the market shifting towards fullstack with Angular.
We started the training smoothly, but by the first morning, Loïc hit me with the truth: if I wanted to do everything thoroughly plus the exercises in that short amount of time, it would be impossible.
So we switched to a full demo format, super dense, but crystal clear.
It gave me perspective and exposed me to all the key topics: NgRx, Nx, Module Federation, etc.
Now I’ve got all the materials, I know exactly what to focus on to go further. Honestly, I didn’t expect to learn that much in such a short time.
ContextFull 5-day training
ReviewI’ve been a full-stack dev for over 10 years, mostly backend-oriented. I always found RxJS unnecessarily complex, and NgRx completely overkill.
But this training changed my perspective.
Loïc made everything clear, logical, and above all, applicable.
He doesn’t just throw concepts, he ties them to real-world use cases. You can tell he masters it deeply, and that he genuinely loves teaching. It’s contagious.
Context1h30 per evening for 4 days, total 6 hours
ReviewSuper intense training. In just 6 hours spread across a few evenings, we covered a massive amount of topics.
It wasn’t possible to dive deep into everything, but it gave me a clear view of the Angular ecosystem and what I need to focus on next.
Perfect to get perspective, prioritize, and unlock stuff we usually just skim over.
Context1-day training for 10 people to assess the current state and share best practices
ReviewWe needed an expert external perspective on our Angular stack.
In one day, Loïc gave us a clear assessment, identified weak spots, and flagged risks we hadn’t seen.
Even for experienced devs, we all learned something new.
Context1-week Angular bootcamp with a team of 5 developers
ReviewThere were 5 of us, with very different skill levels.
I was a beginner, another teammate was already advanced, yet we all learned something.
Loïc adapted, gave tougher exercises to those who progressed faster, while still taking time with others.
Five days like that are rare. We really had time to dig deep.
Context“Fullstack Web Dev” module for a group of ~35 students, 1 week every 3 weeks.
ReviewHonestly, it’s the only course where I actually learned something.
It’s the most interesting course of the year.
First time a teacher comes in with such high-quality materials.
