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.
Explore Cassandra's internal mechanisms through practical labs on simulated clusters, analyze dynamic partitioning and multi-DC replication, model optimized CQL schemas for real workloads, test tunable consistency on enterprise cases, produce a validated deliverable data diagram.
Install a multi-node cluster in-person on dedicated servers, configure gossip protocol and hinted handoff for resilience, use nodetool for real-time monitoring, apply JVM tuning best practices, simulate hybrid cloud deployments, generate professional cluster health reports as deliverables.
Profile slow queries with CQL tracing, optimize secondary indexes and materialized views, test compaction strategies on massive datasets, integrate application caching, analyze bottlenecks via Prometheus metrics, perform before/after benchmarks, produce a personalized optimization guide for enterprise cases.

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.
