Learning objectives

  • Install and configure Express.js for a backend project
  • Develop a web server with dynamic routing
  • Implement middlewares to secure routes
  • Handle HTTP requests and JSON responses
  • Build a complete REST API with database
  • Deploy the application on a cloud host

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 Express.js, your backend projects stagnate: 40% of junior devs lose 2 weeks on basic setups, exposing to security flaws (80% of breaches via unprotected routes, source OWASP).

  • Trained competitors deploy 3x faster, clients flee slow apps (churn rate +25%).

  • Unmanaged bugs cost 500€/incident in prod.

  • Invest 28h to avoid these pitfalls, master Express and multiply freelance opportunities tomorrow.

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.
