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 evolutions of Express 2026 with quick installation via npm, configuration of a high-performance server, creation of dynamic routes, and custom middlewares for logging and authentication. Practice on concrete REST API cases, integrate data validators with Joi, test in real-time with Postman, and produce a first deployable functional prototype, while exploring Node.js optimizations for immediate scalability.
Dive into developing complete REST APIs under Express 2026, implement secure CRUD operations, manage request validation with express-validator, add intelligent pagination and sorting for large data volumes. Work on practical exercises with MongoDB databases via Mongoose, integrate lifecycle hooks for auditing, test endpoints with automated suites via Jest, and deliver a paginated API ready for enterprise production.
Strengthen your Express 2026 APIs against common threats by implementing stateless JWT authentication, configuring advanced CORS for cross-origin frontends, enabling rate limiting with express-rate-limit, and helmets for secure headers. Apply these techniques to real microservices scenarios, practice simulated attacks like SQL injection and XSS, integrate OAuth2, and generate reports on fixed vulnerabilities, ensuring GDPR compliance for your professional projects.
Design distributed microservices architectures with Express 2026, enable Node.js clustering for high availability, integrate Redis for caching and shared sessions, use Kafka for asynchronous messaging between services. Develop practical exercises for service discovery with Consul, test resilience under load with Artillery, monitor via Prometheus and Grafana, and deploy a scalable cluster simulating an enterprise ecosystem, with deliverables ready for Docker.
Finalize your skills by deploying Express 2026 apps in production via Docker and basic Kubernetes, configure CI/CD with GitHub Actions, integrate PM2 for process management and New Relic for real-time monitoring. Practice zero-downtime deployments, analyze logs with Winston and ELK stack, optimize performance under high traffic, and produce a complete pipeline with observability dashboard, certifying your skills for critical professional environments.

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.
