Learning objectives

  • Design complex GraphQL schemas with advanced types
  • Implement optimized and secure resolvers
  • Master mutations and real-time subscriptions
  • Optimize performance via caching and batching
  • Integrate GraphQL into existing stacks
  • Debug and secure production-ready GraphQL APIs
  • Deploy scalable GraphQL servers

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 GraphQL mastery, your REST APIs overload servers with 70% useless data, mobile apps see loading times explode to 5s, leading to 40% user drop-offs according to Google benchmarks.

  • Teams lose 2x more time debugging N+1 issues, bandwidth costs rise 50% in production.

  • Risk obsolescence against over-optimized competitors?

  • With this training, divide latency by 3, boost customer satisfaction by 35%, scale without limits, and win premium contracts right back at the office.

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.
