Don't let this gap widen
Without this advanced TypeScript training, your apps risk 40% more runtime bugs due to loose types, doubling debug time (up to 20h/week lost).
Teams lose scalability: JS to TS migrations fail 60% of the time, hindering enterprise projects.
Recruiters discard 70% of CVs without advanced types expertise.
Save 500h/year in production, avoid costly downtimes (15k€/incident), go from junior to expert in 4 days to boost salaries by 20%.
Dive into complex types by practicing on VS Code and Node.js, build conditional unions to validate API data, manipulate mapped types through interactive exercises on real datasets, test intersections for nested objects, produce a first robust typed deliverable that compiles without errors, gain fluency to code faster and bug-free.
Explore advanced generics in TypeScript Playground, create templated functions for arrays and objects, apply generic constraints to concrete cases like REST APIs, optimize with utility types like Partial and Pick, complete collaborative pair exercises, generate a reusable generic module, transform your habits to develop scalable libs in a snap.
Master decorators by integrating Webpack and Angular CLI, code decorators for logging and automatic validation, structure namespaces and modules for large projects, test on a real e-commerce case with typed authentication, collaborate live to debug, produce an optimized typed bundle, discover tips that boost your productivity by 40% starting tomorrow.
Finalize with a complete project in React or Node.js, migrate a JS codebase to advanced TypeScript, integrate everything via typed hooks and Express routers, analyze performance with tools like TSC and Jest, review best practices in a group, deliver a production-ready GitHub repo, leave with a concrete portfolio that impresses recruiters and clients.

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.
