Hi, I'm
Valerio Mattera,
a Full Stack engineer
Know moreAbout me
I'm an experienced full stack engineer. On the Front End, my areas of expertise include TypeScript, React, Next.js, React Native, and state management libraries. On the Backend, I have experience building RESTful and GraphQL APIs with Node.js, Express, Nest.js, and Serverless.
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.
