Why this program matters
Without this advanced training, your Java apps risk chronic memory leaks, +30% debug time on legacy code, and 20% loss in competitiveness against Spring Boot competitors.
Poorly managed microservices cause 15h/week downtimes, with salary costs exploding by 50k€/year.
Developers stagnate, turnover rises 25%, and companies lose cloud contracts.
Master it or suffer technological obsolescence and critical bugs impacting 40% of users.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
