About Me

My Introduction

Hi I'm João Cruz. I'm 21 years old. I program applications as a hobby and I'm actively expanding my expertise into areas like 3D modeling, sound design, and music production.
I'm a full-stack developer with predominant focus on Node.js, experienced with databases like PostgreSQL and MongoDB. I'm also proficient in Markdown due to my extensive use of Obsidian for documentation and note-taking. I'm passionate about working on open-source projects and exploring new technologies.
