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.
Dive into advanced CockroachDB architecture by installing a multi-node cluster on Kubernetes, configure ranges and replication for high availability, explore zones and multi-regions through practical exercises on real business cases, generate topology diagrams, test automatic failover with CockroachDB tools, produce an initial documented scaling plan for your ongoing project.
Master distributed transactions in CockroachDB by implementing serializable isolation on massive datasets, practice MVCC and contention via advanced SQL, simulate e-commerce scenarios with concurrent conflicts, optimize distributed locks on a Kubernetes cluster, analyze performance with EXPLAIN ANALYZE, develop resilient stored procedures, validate with automated unit tests for professional applications.
Configure CockroachDB resilience by defining survival goals and zone configs for fault tolerance, practice incremental backups and point-in-time recovery with cockroach-dump, test chaos engineering on the cluster using tools like Chaos Mesh, restore data after simulated outages, monitor asynchronous replication, produce tested DRP reports, apply to your ongoing project for zero downtime in enterprise settings.

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.
