Learning objectives

  • Optimize Rails performance with advanced caching and indexing
  • Build scalable and secure GraphQL APIs
  • Implement microservices architectures with Rails
  • Deploy applications on Kubernetes and CI/CD
  • Secure apps with JWT, OAuth, and advanced audits
  • Master end-to-end testing with RSpec and Capybara

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 expert Rails mastery, your apps suffer 40% higher downtimes, maintenance costs explode x3 according to Stack Overflow surveys, scalability blocked limits growth to 20% of potential, junior teams multiply security bugs (85% breaches via poorly secured APIs, Verizon DBIR), competitors outpace with fluid microservices, estimated revenue losses 150k€/year per unoptimized app, frustrating to stagnate while peers deploy worldwide.

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.
