Why this program matters

  • Without expert Rails mastery your apps suffer 25% downtime during traffic peaks, server costs surge 40% from missing caching, absent GraphQL APIs slow client innovation with +30% development time, OWASP security attacks expose you to 1M€ in annual GDPR fines, manual deployments waste 15h/week in production, mismanaged microservices cause 50% of critical bugs, you stay locked on slow monoliths while competitors scale 10x faster, and you invest 14h to multiply ROI x5 starting tomorrow.

Rails Expert training objectives

  • Optimize Rails performance with advanced caching and Sidekiq.
  • Implement scalable and secure GraphQL APIs.
  • Design microservices architectures in Rails.
  • Master zero-downtime deployment on Kubernetes.
  • Strengthen security against OWASP Top 10 attacks.
  • Automate end-to-end tests with RSpec and Capybara.
  • Generate advanced metrics with New Relic.

Rails Expert curriculum: 2 modules over 2 days

Module 1 : Performance and Advanced APIs: Caching, Sidekiq, GraphQL (Ruby tools, live exercises).

Dive into Rails optimization by refactoring a real app with Redis for fragment caching, queuing complex jobs via Sidekiq to scale asynchronous tasks, and building a GraphQL API from scratch with secure mutations. Test everything with live coding on shared VS Code, analyze before/after metrics to boost performance by 300%, and leave with a personally optimized project and ready-to-deploy configs.

Module 2 : Architecture and Deployment: Microservices, Security, Kubernetes (RSpec, Helm, OWASP).

Advance to professional architecture by decomposing a monolith into Rails microservices communicating via gRPC, strengthen security against injections and XSS with live OWASP audits, deploy zero-downtime on Kubernetes using custom Helm charts, automate E2E tests with RSpec/Capybara in TDD, monitor with custom New Relic dashboards, pair-code on concrete business cases like scalable e-commerce, and obtain deployable deliverables with an implementation plan for production.

How Rails Expert skills are assessed

  • Daily technical quizzes, pair-programming code audits, final deployed project.

How the Rails Expert course is taught

  • 90% hands-on live coding, exercises on real apps, individualized feedback.

Our method

How Learni guarantees the quality of your Rails Expert training

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.
