Learning objectives

  • Set up optimized Fastify servers for high-load production
  • Implement lifecycle hooks and advanced Ajv validation schemas
  • Develop custom plugins and scalable microservices
  • Integrate JWT, rate limiting, and PM2 clustering
  • Perform exhaustive tests with Tap and Artillery
  • Benchmark performance x10 vs competitors
  • Deploy in secure Docker/K8s containers

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 expertise, your APIs lag at 300ms latency vs 10ms, causing 45% user drop-offs and -25% conversions.

  • Weak scalability downtimes cost 15k€/month in lost revenue.

  • Competitors on Nest/Express outpace you, dev talents flee to modern techs.

  • 70% backend teams stagnate without framework upgrades, risking failed security audits and GDPR fines.

  • Lose tech lead: slow APIs = unhappy clients, 30% churn.

  • Invest 28h for x10 performance, zero vulnerabilities, undisputed leadership.

Module 4Security, Testing, Deployment: JWT, Tap, Docker (production ready)

Secure with JWT guards and rate-limiter, test unit/integration via Tap, benchmark Artillery for 99.9% SLA, containerize with Docker/K8s, deploy CI/CD GitHub Actions, finalize capstone certifying project, leave with bulletproof production stack and total confidence.

Evaluation method

  • Interactive technical quizzes, graded coding exercises, final complete API project, Qualiopi certification.

Learning method

  • Live screen-share coding workshops, pair-programming challenges, anonymized real client cases.

Methods, materials and delivery

The Training Fastify Expert - Ultra-Fast and Scalable APIs program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

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.
