Learning objectives

  • Master Fastify's hooks and plugins architecture for modular apps
  • Optimize API performance with streaming and built-in caching
  • Implement robust schema validation via AJV and JSON Schema
  • Secure routes with JWT authentication and rate limiting
  • Deploy scalable APIs in production with PM2 and Docker
  • Write advanced unit and integration tests with Tap
  • Analyze and monitor performance in real-time

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 advanced Fastify, your Node.js APIs remain slow: 40% of users abandon if latency >2s, costing 25% lost revenue according to Google.

  • Scaling impossible without plugins, leading to downtimes at 500€/min.

  • Competitors on Nest/Express outpace you with 3x more requests/s.

  • Weak security exposes to breaches: 60% of 2023 API leaks via poor JWT management.

  • Invest 35h now to avoid 10k€ urgent refactoring and boost employability by 30%.

  • Don't miss performance leadership!

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.
