About me

Self-taught Frontend Developer specialized in React, TypeScript, Tailwind CSS and Astro. I combine scalable architectures with performance optimization (Core Web Vitals, lazy loading, code splitting) and a careful visual sensibility. I have experience taking complete products from idea to production: SaaS, desktop apps (Electron/Tauri) and CLIs.
