Why this program matters
Without intermediate Rails mastery, your web apps risk critical vulnerabilities: 70% of breaches stem from poorly managed Auth configs, per OWASP.
Develop 2x slower without optimized ActiveRecord, leading to exploded project timelines and +50% costs.
Lose 30% of clients to slow performance (load times >3s).
Avoid deployment downtimes (40% failures without CI/CD) and N+1 query bugs freezing your databases.
Invest now to scale confidently, boost productivity, and retain users.
Program
Module 1Routing and Controllers: Master Nested and RESTful Routes (Rails 7, Helpers)
Dive into advanced routing by building an e-commerce project, configure controllers with before_actions and strong parameters, generate dynamic partial views using HAML or Slim, test live with practical exercises on real cases like a multi-author blog, produce custom scaffolds ready for deployment.
Module 2ActiveRecord Models: Complex Associations and Optimized Queries (ActiveRecord Gem)
Build has_many_through and polymorphic relationships by modeling a collaborative task management app, migrate databases with automated seeds, optimize N+1 queries using includes and eager_load, apply custom validations and callbacks, complete exercises on real datasets to deliver a robust data model.
Module 3APIs and Security: Build JSON Endpoints with Authentication (Devise, JWT)
Create a RESTful API for a mobile app integrating Devise for auth, Pundit for permissions, generate secure JWT tokens, test with Postman and RSpec, simulate intrusion scenarios to strengthen security, produce a Swagger-documented API blueprint with practical challenges for immediate mastery.
Module 4Optimization and Deployment: Performance and Live Production (Sidekiq, Heroku)
Boost performance with Redis caching and Sidekiq background jobs on a complete final project, profile with New Relic, deploy to Heroku via automated Git push, configure Puma and Nginx, integrate CI/CD tests with GitHub Actions, conclude with a deliverable: a live, scalable Rails app ready for production.

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.
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.
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.
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.
