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 Express 2026 from the morning with guided installation via npm, basic server setup and first live tests, then dive into dynamic routing to handle GET, POST, and PUT, integrate custom middlewares for logging and validation, complete practical exercises on concrete cases like a simple CRUD, end with a mini-project delivered and tested in group, alternating quick theory and hands-on code to anchor your backend skills from the first day.
Deepen REST APIs with Express 2026 by implementing JWT authentication and MongoDB connection for data persistence, structure communicating microservices via HTTP, optimize with caching and advanced error handling, practice on a complete e-commerce project including secure endpoints and unit tests, deploy in Docker container for production simulation, exchange feedback in plenary session, leave with annotated source code and deployment checklist, strengthening your professional skills in scalable backend.
The Training Express 2026 - Developing High-Performance Backend APIs program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

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.
