Don't let this gap widen
Without SolidJS expertise, your apps suffer excessive re-renders, inflating CPU usage by 50% and latency by 40% according to Web Vitals benchmarks.
Lose 30% of mobile users frustrated by heavy frameworks like React, while agile competitors on SolidJS scale 10x without lag.
Risk exploding cloud costs (+200% on AWS), slow updates, and rapid obsolescence in 2024.
Invest now for native performance, fine-grained reactivity, and a sustainable competitive edge, avoiding these costly pitfalls that hinder your dev career.
Dive into the heart of SolidJS, manipulate signals for granular reactivity, code effects and memos to avoid unnecessary re-renders, complete exercises on dynamic dashboards, analyze real mobile optimization cases, produce an ultra-smooth prototype that outperforms React in performance.
Master global stores and fetch resources for data-driven apps, integrate nested contexts without boilerplate, develop exercises on complex e-commerce, simulate real asynchronous flows, generate reusable shared state components, boost your code to expert scalability.
Push performance to the max with built-in profiling and lazy loading, refactor legacy apps to SolidJS, conduct React vs Solid benchmarks, code advanced hooks patterns, test on high-load cases, deliver an optimized module reducing latency by 70%, ready for production.
Integrate SolidStart for native routing and SSR, set up Vercel/Netlify deployments, build a full-stack capstone project, automate CI/CD with end-to-end tests, manage advanced authentication, deploy a live expert app, leave with a concrete portfolio and production-ready skills.

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.
