Matteo Valerio

I’m a full-stack developer with 5+ years of experience building and evolving web applications across both startup and enterprise environments. I currently work at Air (Connected Mobility), where I focus on Node.js, React, and TypeScript-based systems.

I’m particularly interested in understanding and improving existing codebases, especially APIs, and in navigating the real-world trade-offs behind system evolution.

I also contribute as a technical content author for Hyperskill (JetBrains Academy).
