Learning objectives

  • Set up a production-optimized Fastify server
  • Implement advanced custom plugins and hooks
  • Manage JWT authentication and secure authorization
  • Optimize performance with streaming and Redis caching
  • Validate JSON Schema using Ajv and decorators
  • Deploy and monitor with PM2, Docker, and Prometheus

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without Fastify, your Node.js APIs top out at 10k req/s, vs 100k+ with Fastify (official benchmarks).

  • Risk +300% response time under load, downtimes at 15k€/h (Gartner), teams stuck on slow Express, 50% inflated infra costs.

  • Clients flee to scalable competitors.

  • 28h investment = x10 perf, -40% hosting, immediate ROI on critical projects.

  • Don't let your APIs sink your business.

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.
