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 the basics of JPA through practical exercises on creating annotated entities, attribute mappings, and simple relationships like @OneToMany, using Hibernate as the main implementation. Configure a Maven project with persistence.xml, test CRUD operations on an embedded H2 database, and analyze generated SQL logs to understand the entity lifecycle. Deliverables: functional entity and unit test report.
Dive into JPQL queries for complex selects, joins, and aggregates, then move to the Criteria API for dynamic type-safe queries. Practice on real enterprise cases with Spring Boot, integrate projections and fetch joins to optimize performance, and debug via Hibernate Statistics. Exercise on a complete e-commerce scenario, producing paginated and exportable reports.
Explore bidirectional relationships, cascades, and lazy loading with concrete examples on PostgreSQL, configure class inheritance via Single Table or Joined Strategy. Integrate Hibernate Validator for entity validation, manage reference cycles, and implement custom converters. Practical work on a Spring Boot REST API, resulting in a robust and documented data model.
Master EntityManager and transactions with Spring @Transactional, configure Ehcache or Infinispan caching to reduce database accesses by 50%. Analyze deadlocks, optimize flushes and merges, and test concurrency with JUnit. Apply to a banking business case, generating performance metrics and an optimization guide for production deployment.
Integrate Spring Data JPA for automated repositories, enable Hibernate Envers for modification audits, and deploy on Docker with Flyway for migrations. Develop a complete microservice with JWT security, test via Postman, and profile performances. Deliverables: deployable application, Git source code, and professional skills certificate.

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.
