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 1Outbox Pattern Fundamentals: Modeling Distributed Transactions (Debezium, CDC, PostgreSQL)
In-depth analysis of dual-write problems and solutions via Outbox Pattern, installation of a Debezium environment with PostgreSQL WAL logs, implementation of a first transactional relayer on a concrete e-commerce case, practical exercises on change capture with custom poller, generation of idempotent Kafka payloads, code review to validate ACID consistency in your professional projects.
Module 2Advanced Outbox Pattern Implementation: Hybrids and Scaling (Spring Boot, Kafka Streams, Idempotence)
Development of a hybrid transactional Outbox with Spring Boot and Kafka Connect, configuration of deduplication via exactly-once semantics, load testing on simulated Kubernetes clusters, integration of intelligent retry mechanisms and dead-letter queues, practical cases on monolithic migration to event-driven microservices, production of monitoring metrics for proactive alerts, immediate valorization of certified skills in enterprise.
Module 3Outbox Pattern Deployment and Optimization: Resilient Production (Quarkus, Observability, CI/CD)
CI/CD deployment of a complete Outbox system with Quarkus and Helm charts, observability instrumentation via Prometheus and Grafana for end-to-end traceability, network failure simulations and automated recovery, performance optimization for 10k+ TPS, security audit and GDPR compliance on sensitive events, finalization of a deliverable red thread project, post-training support for rapid integration into professional production.

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.
