Learning objectives

  • Master conditional types and mapped types for advanced professional TypeScript skills
  • Implement powerful generics in scalable enterprise architectures
  • Optimize strict typing to reduce runtime errors in certified training
  • Design custom utility types adapted to complex JavaScript projects
  • Integrate expert TypeScript with Next.js for high-performance applications
  • Develop typed design patterns to strengthen enterprise skills

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.

Module 1Advanced TypeScript Types: conditional types, mapped types and generics (practical exercises, enterprise cases)

Dive into the deep mechanisms of conditional types and mapped types through interactive workshops, refactoring existing JavaScript code to infallible typing, analyze real cases of scalable e-commerce applications, implement parameterized generics for complex data structures, test live with VS Code and TypeScript compiler, produce reusable utility types delivered at the end of the day to immediately boost your professional projects.

Module 2TypeScript Optimization: design patterns and Next.js integration (real projects, typed deployments)

Apply advanced patterns like typed Builder and Factory in enterprise API simulations, integrate TypeScript with Next.js 14 for high-performance SSR apps, optimize performance via advanced modules and error boundaries, develop a complete scalable dashboard project with typed authentication, deploy on Vercel with configured CI/CD, evaluate productivity gains, receive ready-to-use templates and a personalized code audit for immediate production deployment.

Evaluation method

  • Continuous evaluation through practical exercises and real-time code reviews
  • Final individual project: complete typed Next.js architecture
  • Expert quiz on advanced types and Qualiopi recognized certification

Learning method

  • 70% hands-on practice with exercises and real projects
  • 30% theory via Fortune 500 company case studies
  • Adaptive pedagogy based on participants' levels
  • Professional tools: VS Code, TypeScript 5+, Next.js playgrounds

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.
