🧑‍💻 JavaScript Web Developer

I develop Web Applications and RESTful APIs.
Whether frontend or backend, as a Full-Stack Web Developer I unify both.
I'm a curious, open-minded and kind individual with a great passion for coding.


✅	JavaScript ES6+, TypeScript, MERN Stack
✅	Single Page Web Applications (ReactJS)
✅	Layout, Design and Typography (HTML, CSS)
✅	RESTful APIs (ExpressJS)
✅	Database (MongoDB, SQL)
✅	Agile Methodologies (Kanban, Scrum)
✅	Version Control (Git), Collaboration (CI)
