Background

Frontend Developer specializing in React/TypeScript architectures, from IE5 compatibility hacks to modern Server Components.

Currently building with React ecosystem, Node.js backend services, and pixel-perfect UI implementations. Remote-first since 2016, EU work authorized (Italian citizenship), seeking senior frontend role focused on technical excellence and product engineering.
