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 1Express Middleware: Customization and Advanced Security (validation, rate limiting, CORS)
Dive into creating custom Express middleware to validate inputs with Joi and express-validator, configure rate limiting with express-rate-limit and advanced CORS management, integrate structured logs via Winston, perform exercises on vulnerable APIs to fix live, produce a reusable middleware tested on real enterprise cases, and validate via code review with the trainer for immediate production mastery.
Module 2Expert Express Routing: Dynamic Routes and Error Handling (express-router, API versioning)
Build modular Express routers with nesting and advanced parameters, implement API versioning via express-versioning, handle global and local errors with custom handlers, connect to MongoDB via Mongoose for optimized CRUD, develop a red thread project on a complete e-commerce API, test with Postman and basic continuous integration, obtain scalable routes ready for the team with generated Swagger documentation.
Module 3Express Scalability: Clustering, Sessions, and Caching (PM2, Redis, load balancing)
Start native Node.js clustering in Express with PM2 for high availability, manage distributed sessions via connect-redis and Redis, implement intelligent caching for API queries, simulate high loads with Artillery for benchmarks, optimize memory and CPU on real high-traffic enterprise cases, produce a deployable cluster with zero-downtime configuration, and analyze metrics for measurable performance gains during the session.
Module 4Express Deployment and Monitoring: Tests, Docker, and Observability (Jest, Supertest, Prometheus)
Write unit and integration tests for Express with Jest and Supertest covering 90% of code, containerize the app via Docker Compose multi-services, deploy to cloud with CI/CD GitHub Actions, integrate Prometheus-Grafana monitoring for real-time alerts, debug live incidents on the red thread project, finalize with hot-reload and reusable blueprints, leave with an expert portfolio highlighting your certifying skills in the enterprise.

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.
