Cristian started his career as a full-stack .Net developer more than seven years ago, but in the past couple of years, he's been in love with the JavaScript ecosystem. Nowadays, he's a huge fan of React, Remix, and Next.js. For most of his career, he's worked on financial applications but is eager to explore new domains. Cristian has always been the "go-to guy" for issues in all of his previous projects because of his ability to grasp the industry rapidly.
