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 Performance: profiling and optimization (RubyProf, StackProf, benchmarks)
Dive into fine-grained Ruby performance analysis using RubyProf and StackProf on real enterprise cases, identify code hotspots, perform before-after optimization comparative benchmarks, apply memoization, fibers and performant data structures, produce a detailed report with quantified metrics on your red thread project, immediately transforming your developments into competitive assets for the company.
Module 2Ruby Concurrency: fibers, threads and async (Ractor, Async)
Explore advanced concurrent programming in Ruby with Ractor and fibers for 2026, implement parallel tasks without blocking on massive datasets, integrate Async for reactive APIs, test resilience with simulated load using tools like Siege, develop a scalable concurrent service, analyze deadlocks and race conditions live, deliver a thread-safe module ready for professional production.
Module 3Ruby Memory: GC tuning and allocation (ObjSpace, benchmarks)
Master the Ruby garbage collector via ObjSpace to minimize pauses in critical apps, profile object allocations on large projects, apply enterprise-adapted GC tuning strategies, simulate high-memory loads with heap dumps, optimize persistent objects and pools, generate a custom memory monitoring dashboard, thereby boosting the efficiency of your professional Ruby deployments.

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.
