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 Resilience4j 2026 through quick installation with Maven or Gradle, explore essential modules like Circuit Breaker and Retry, complete practical exercises on simple Spring Boot applications, configure in-memory backends, test fallback behaviors, produce detailed logs, and validate initial real-world production use cases in simulated environments, building professional skills from day one.
Dive into advanced Circuit Breaker configurations with custom thresholds and half-open states, implement adaptive Retry on external REST APIs, integrate custom events for monitoring, generate Prometheus metrics, simulate load scenarios with JMeter, analyze impacts on availability, and deploy Resilience4j decorators in a real microservices project, optimizing enterprise resilience.
Master Rate Limiter with the Token Bucket algorithm to limit API calls, configure Bulkhead to isolate threads and prevent error cascades, apply these patterns to cloud-native services, test under stress with Artillery, measure performance via Grafana, integrate with Spring Boot Actuator, develop high-load e-commerce use cases, and produce resilience reports for the DevOps team.
Explore Time Limiter for long-running operations with CompletableFuture, implement distributed Cache coupled with Caffeine, synchronize with Resilience4j 2026 in reactive WebFlux streams, perform asynchronous benchmarks, manage distributed timeouts via Hazelcast, test consistency in Kubernetes clusters, deploy in hybrid environments, and generate custom dashboards for professional certifying supervision.

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.
