The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
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 1Theme: CQRS Applied to Dataviz (D3.js, data flow structure, business cases)
Participants discover the CQRS pattern applied to data visualization. They explore the basics of D3.js, create separate flows for commands and queries, and build a first simple dashboard with real data. Practical exercises guide the setup of structures and the display of basic charts.
Module 2Theme: CQRS and Interactive Dashboard (D3.js, events, real-time updates)
This day deepens the construction of dynamic dashboards. Learners use CQRS to manage interactions, integrate user events, and optimize renderings with D3.js. Real business cases allow testing real-time updates and delivering a functional prototype.
Module 3Theme: CQRS for Advanced Dataviz (D3.js, aggregations, performance)
Trainees design complex visualizations by applying CQRS. They work on data aggregations, improve query performance, and use D3.js for rich charts. Exercises on large datasets lead to the creation of an optimized dashboard deliverable.
Module 4Theme: CQRS and Dataviz Deployment (D3.js, integration, best practices)
The training concludes with deployment and maintenance of solutions. Participants integrate their dashboard into a professional environment, apply CQRS best practices, and test scalability with D3.js. A final project validates acquired skills and provides a ready-to-use deliverable.

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.
