Build hierarchical components by passing dynamic props, handle keyboard and mouse events with reactive handlers, implement conditional lists and loops, practice on real cases like a todo-list, generate reusable components, feel the fluidity that makes you want to code faster.
Discover Signals for ultra-reactive state, create Stores for global state, derive computed values automatically, apply to complex forms with real-time validation, practice on simulated multi-user apps, obtain performant deliverables that outperform competitors in speed.
Install Solid Router for dynamic routes, integrate API calls with fetch and Suspense for lazy-loading, manage errors and loading states, develop a complete e-commerce app with persistent cart, test in real conditions, produce a deployable project that impresses with its reactivity.
Profile your apps for optimal performance, write unit tests with Vitest, configure production build, deploy on Vercel or Netlify in one click, optimize for mobile and SEO, finalize a personal capstone project, leave with a pro portfolio ready to boost your career.

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.
