About me

I'm an experienced engineer with a focus on Frontend development. My areas of expertise include TypeScript, React, React Native, and frameworks like Next.js and Remix. Additionally, I have experience in Backend development, primarily with Node.js.

When I'm not working or studying, I enjoy a range of activities. I'm an avid video game enthusiast, a regular at the gym, I read books, comics and manga and I'm a keen follower of TV series and sports, with a special interest in Formula 1.

If you're interested in collaborating or simply wish to have a chat about whether Lewis Hamilton is the GOAT or not, feel free to contact me at info@valeriomattera.com.
