Don't let this gap widen

Why this program matters

  • Without Fastify, your Node.js APIs remain slow, losing 40% speed vs competitors, costing 25% of customers in mobile e-commerce where 3s latency = cart abandonment.

  • Developing with Express doubles coding time, multiplying security bugs by 3 according to Stack Overflow, exposing to costly breaches (average 4M€).

  • Are you missing freelance opportunities at 80€/h higher?

  • 70% of tech companies require lightweight frameworks like Fastify to scale.

  • Are you risking obsolescence against NestJS or Hapi, or boost your career today?

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.
