Hi, my name is
Raphael Barreiro.
I develop online things.
I'm a Front-End Dev who loves the programming universe. My goal is to build exceptional web experiences.
01. About Me
Hello!! Good to see you here! My name is Raphael and I turned out te be a big enthusiast of the web design/Front-end universe. I've always been a "DIY" guy, regarding all my daily hardware and softwares.
"My PC won't start? No problem, I can fix it."
Since I chose the DEV area as my professional life, I've been studying hard. I've already completed 52 courses directly related to programming (with certificates), 3 degrees and I'm on my way to my fourth one: "FullStack Development: Java + Angular".
I have quite a solid professional background, since I worked at a big engineering company, at a medical education startup and as autonomous. Find more details at my LinkedIn.
Here are a few technologies I’ve been working with/studying recently:
- React.js
- Typescript
- Javascript ES6+
- JQuery
- Node.js
- Framework7
