Don't let this gap widen
Why this program matters
Without advanced Rails expertise, 70% of apps crash under 1000 simultaneous users, costing 40k€ in annual downtime.
Security vulnerabilities expose to breaches (average 250k€ client data loss).
Development time doubles on legacy refactoring, slowing growth 2x.
Productivity drops 50% without caching/async job optimization.
85% of trained devs scale apps 10x faster, avoiding obsolescence against competitors.
Invest or risk irreparable market lag.

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.
