Don't let this gap widen
Without advanced Ruby training, your Rails apps risk chronic memory leaks costing up to 25% CPU resources in production and 10k€/year in unnecessary infrastructure.
Undetected bugs via TDD tests impact 35% of users, generating 15% churn and negative App Store reviews.
Your legacy code slows iterations, tripling feature delivery times, while competitors scale 5x faster with optimized metaprogramming.
Are you losing freelance opportunities at 80€/h?
Invest now to avoid these costly pitfalls and dominate the Ruby market.
Dive into the secrets of advanced Ruby by creating your own DSLs with define_method and metaclass, test live on IRB for concrete exercises on dynamic inheritance, build a personal mini-framework by refactoring existing code, leave with snippets ready to integrate into your Rails projects to boost productivity from tomorrow.
Install and configure powerful Gems like Sidekiq for asynchronous jobs and Puma for multi-threading, perform practical exercises on memory optimization with heap dumps, integrate Rubocop for clean code, develop a scalable worker in real conditions, obtain tested deliverables to accelerate your apps by 40% in production.
Build robust JSON APIs with Rails 7 by implementing GraphQL via Graphene, secure with Devise and Pundit on enterprise cases, code advanced controllers with concerns, test real attack scenarios, produce a complete deployable API prototype, transform your skills to deliver enterprise-ready backends in record time.
Master end-to-end tests with RSpec and Capybara on complex apps, profile performance via New Relic to track bottlenecks, containerize with Docker and deploy via Capistrano to staging, perform a complete audit of a legacy project, leave with a portfolio of certified deliverables ready to scale deployments without downtime.

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.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
