Crescenzo in a few words
A software developer since 2016 with experience mostly with backend but i've dabbled with front-end as well whenever there was the need. Mainly experienced with Ruby and Ruby on Rails, but in the past I've worked on e-commerce projects with Java and more recently a little bit with Kotlin and Spring. I like trying new challenges and figuring out stuff. I pride myself in writing code that is well tested and easily readable by my fellow developers.
