Gabriel Romualdo

Young web developer (in high school) looking to build something new with code and make a name for myself. More at xtrp.io. Formerly known as Fred Adams.

Earth Joined on Aug 11, 2018 https://xtrp.io/

MERN stack, and possibly some Web Assembly

Modern CSS and SASS, and JavaScript with ES6

Firebase and Chrome Extension development, some experience in PHP and Python

I like to release my projects as a surprise to add an extra 🔥 effect.

Would love to hear from you if you'd like to work with me on a project idea, or are just looking for a dedicated open source contributor for a repo. I respond to DMs here are DEV or through my email (see my website at xtrp.io).
