Raphael – React, Node.js, JavaScript

Raphael has been in the IT industry for more than 15 years, and for the last 7 of them, he has been dedicated to working with a Javascript environment. Like every full-stack developer, Raphael has his hidden preferences: he leans towards the front-end but is also no slouch in the back-end business.

It's worth mentioning that Raphael is a fan of lifelong learning: he is thrilled about an opportunity to acquire new skills and continuously deepen his expertise. He has a passion for making technology work for people and loves nothing more than solving challenges.

Raphael's extensive background as a tech teacher will greatly help when it comes to the discussion of complex topics and mentoring less experienced teammates.
