The Learni story
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
Why this program matters
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.
Program
Module 1Ruby Metaprogramming: Customize the Language for Complex Projects (define_method, eigenclass)
Dive into Ruby's internal mechanisms through advanced metaprogramming, create custom DSLs for your business needs, dynamically manipulate classes and modules with eigenclass and method_missing, perform practical exercises on a real enterprise case like a lightweight ORM, produce a functional, tested, and documented deliverable for immediate team reuse.
Module 2Ruby Performance: Profiling and Optimization (ruby-prof, benchmark-ips, garbage collector)
Analyze bottlenecks in your Ruby apps with ruby-prof and stackprof, optimize code via benchmark-ips on production scenarios, tune the G1 garbage collector to reduce latency, apply concrete refactorings to a red thread project, measure gains of up to 50% in throughput, generate performance reports to demonstrate business value.
Module 3Ruby Concurrency: Fibers and Async for 2026 (Ractor, Async gem, EventMachine)
Explore Ractor for safe parallelism in Ruby 3+, implement fibers and coroutines with Async for non-blocking I/O, integrate EventMachine for scalable websockets, develop a concurrent service handling 10k connections, test under load with practical exercises, produce a 2026-ready prototype deployable in the cloud, highlighting certifiable team skills.
Module 4Advanced Ruby Gems: Packaging and CI/CD (Bundler, RubyGems, GitHub Actions)
Create and publish professional Ruby gems via RubyGems and Bundler, set up advanced CI/CD with GitHub Actions and RSpec, integrate security with Dependabot, package for internal enterprise distribution, build a custom utility gem during a hands-on workshop, validate through code review and automated tests for immediate adoption.
Module 5Ruby Deployment for 2026: Cloud-Native and Monitoring (Docker, Kubernetes, New Relic)
Containerize Ruby apps with multi-stage Docker for efficiency, orchestrate with Kubernetes Helm charts, implement professional monitoring via New Relic and Prometheus, deploy with zero-downtime on a simulated cluster, secure with secrets management, finalize the red thread project with a complete pipeline, obtain a production-ready blueprint to boost your career.

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.
