Don't let this gap widen
Without SolidJS, your React apps overload the DOM, multiplying re-renders by 5 and bloating bundles by 40%, doubling load times and causing 25% of mobile users to abandon.
Competitors are already adopting this 2x faster technology, leaving you with mediocre performance, +20% dev costs, and an obsolete stack.
Lose contracts due to slow UIs, miss tight deadlines, or train now to boost your apps to 60 FPS, reduce bugs by 50%, and dominate the reactive frontend market.
Dive into signals for granular reactivity without a virtual DOM, set up your project with Vite, code your first reactive components through practical exercises on dynamic counters and filtered lists, test ultra-fast live updates, and leave with a ready-to-use template that boosts productivity from day 1.
Build conditional and iterative components with reactive props, apply patterns like children props and portals, complete a hands-on exercise on an interactive product catalog, integrate CSS-in-JS styles, visualize performance gains, and validate your skills with a deliverable mini-project that will impress your peers.
Set up a performant router with lazy loading for fluid SPA apps, implement Stores for shared state without boilerplate, code a dashboard app with simulated authentication and nested navigation, manage API queries via reactive fetch, test seamless transitions, and produce a production-ready functional prototype.
Profile your apps to track memory leaks, apply memos and lazy loading to divide render times by 3, integrate Suspense for streaming, deploy on Vercel with automated CI/CD, finalize a personal capstone project on a collaborative todo app, receive expert feedback and certification, and launch confidently into professional SolidJS.

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.
