Why this program matters

  • Without this training, waste 40% of time on haphazard debugging of poorly structured code, miss 25% performance with mismanaged gems, produce vulnerable APIs exposing your apps to production crashes.

  • 65% of intermediate developers stagnate for 2 years without upskilling, losing 5k€/year in freelance opportunities.

  • Ruby pro competitors land jobs at +30% salary, while your backlog explodes in frustration.

  • Invest 21 hours to double productivity, avoid project delays, and shine in your team.

Program

Intermediate Ruby curriculum: 3 modules over 3 days

Module 1 : Advanced Ruby: classes, modules, inheritance (IRB, practical exercises)

Dive into Ruby's powerful mechanisms, create classes and modules through interactive IRB exercises, explore inheritance and mixins on real-world app cases, produce a reusable module, test live to boost your code right after the coffee break, and leave with pro patterns that transform your scripts into solid libraries.

Module 2 : Gems and Sinatra: dynamic APIs (Bundler, Sinatra, Postman)

Install and manage gems with Bundler on live projects, build a complete REST API in Sinatra, route requests, handle JSON and lightweight databases, test endpoints via Postman in real time, integrate basic authentication, and deliver a functional mini web app that impresses peers and accelerates your daily prototypes.

Module 3 : Testing, optimization, final project (RSpec, profiling, deployment)

Cover RSpec for comprehensive unit and integration tests, profile code to track memory leaks, optimize algorithms on real benchmarks, handle advanced exceptions with custom rescues, complete a fully deployable API project, receive expert feedback, and leave certified with a concrete portfolio ready for GitHub and job interviews.

How Intermediate Ruby skills are assessed

  • Daily interactive quizzes, graded practical exercises, final project evaluated by experts.

How the Intermediate Ruby course is taught

  • 70% hands-on with live coding, 30% applied theory, immediate feedback in small groups.

Our method

How Learni guarantees the quality of your Intermediate Ruby 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.
