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
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Discover the advanced foundations of Ruby on Rails through practical exercises on MVC architecture, configure complex routes with constraints, install and customize essential gems like Devise for authentication, generate scaffolds to accelerate prototyping, analyze real e-commerce application cases, produce a first functional prototype with SQLite database, and receive immediate trainer feedback to consolidate your professional skills.
Dive into data modeling with ActiveRecord, implement has_many, belongs_to, and polymorphic associations, create custom validations and callbacks, migrate PostgreSQL database schemas live, solve exercises on real scenarios like inventory management systems, optimize queries with scopes and eager loading, and deliver a robust data model ready for frontend integration, strengthening your professional backend development skills.
Master advanced controllers with RESTful actions, integrate dynamic ERB views and reusable partials, implement Turbo for reload-free interactions and Stimulus for lightweight JavaScript, manage assets with Webpacker, develop complex forms with nested attributes, test use cases like interactive admin dashboards, debug in real-time with the Rails console, and produce a fluid user interface ideal for modern enterprise web applications.
Build robust JSON APIs with namespaces and versioning, secure with Pundit for authorizations and Rack for middlewares, integrate unit and integration tests via RSpec and FactoryBot, implement JWT authentication for SPA frontends, simulate common attacks and countermeasures, analyze 90% code coverage, deploy a complete API endpoint connected to a simulated React frontend, and validate your certified professional application security skills.
Prepare for deployment by containerizing with Docker and Docker Compose, configure CI/CD via GitHub Actions for Heroku or AWS, optimize for horizontal scaling with Sidekiq for async jobs, monitor performance via New Relic and structured logs, migrate a complete app to simulated production, manage errors with Sentry, perform live hotfixes, and conclude with a deliverable final project, certifying your Rails DevOps skills for scalable enterprise environments.

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.
