Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • Without expert Ruby mastery, 40% of backend apps crash under load according to Stack Overflow surveys, costing SMEs 250k€/an in downtime.

  • Developers stagnate, risking 20% lower salaries vs certified experts, companies lose 30% productivity on legacy refactoring.

  • Avoid career obsolescence and costly audits, invest in scalable skills now to boost ROI on critical projects.

Program

Module 1Ruby Metaprogramming: Advanced Techniques and DSLs (tools, methods, deliverables)

Dive into define_method and metaclass methods to create custom Domain Specific Languages, apply them to concrete enterprise cases like custom APIs, perform practical exercises with advanced IRB and RSpec for testing, produce a functional DSL deliverable by end of day, integrate patterns like secure monkey patching, while optimizing for code maintainability in production.

Module 2Ruby Performance: Profiling and Optimization (tools, methods, deliverables)

Explore stackprof and ruby-prof to identify bottlenecks in expert Ruby applications, optimize with garbage collector tuning and advanced memoization, address real-world high-traffic e-commerce cases, perform benchmarks before/after on legacy code, generate performance reports as deliverables, integrate flamegraphs to visualize hot paths, apply refinements for modularity without global pollution.

Module 3Ruby Concurrency: Threads and Actors (tools, methods, deliverables)

Master Thread and Fiber for Ruby parallelism, implement actor patterns with concurrency-safe queues, simulate I/O-bound and CPU-bound workloads in practical exercises, test with concurrent-ruby gem, develop a resilient worker system as a deliverable, analyze race conditions using debug tools, optimize for cloud scalability with Puma and Sidekiq clusters.

Module 4Ruby Gems and Extensions: Custom C Development (tools, methods, deliverables)

Create bundler-ready gems with rake and yard docs, extend with C via FFI and inline::C for performance hotspots, bundle and push to RubyGems, test cross-platform with Travis CI, produce an optimized gem deliverable for heavy parsing, integrate into an existing Rails app, manage versions and dependencies professionally.

Module 5Ruby Architecture and Deployment: Expert CI/CD (tools, methods, deliverables)

Design Ruby microservices with gRPC and Sidekiq, deploy zero-downtime via Capistrano and Docker, configure monitoring with New Relic and Datadog, automate pipelines with GitHub Actions, simulate production failover in hands-on labs, deliver a complete scalable architecture, obtain Qualiopi certification validating enterprise skills.

Evaluation method

  • Advanced technical quizzes on metaprogramming and concurrency
  • Final project: custom gem deployed with CI/CD
  • Oral interviews and peer code review remotely

Learning method

  • 70% hands-on practice on real enterprise cases
  • Replay videos and interactive materials
  • Hands-on exercises with provided source code
  • Dedicated 24/7 coached forum post-training

Methods, materials and delivery

The Ruby Training - Expert Performance and Scalability Optimization program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Ruby Training - Expert Performance and Scalability Optimization program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Ruby Training - Expert Performance and Scalability Optimization program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

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.

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.
