HEY, I'M CATALIN OBREJA

A full-stack developer focused on building quality software, specialized in ReactJS and NodeJS.

about me

Here you'll find details about me, my passion for coding, and the tech skills I've developed along the way.

Get to know me!

I've been a Web Developer for over 10 years, and before that, I made a living playing professional poker for about four years. My main focus is on Front-End development, which means I handle the parts of websites and apps that you interact with, but I often work on the Back-End too, ensuring everything runs perfectly behind the scenes.

I truly love programming, and that passion has kept me from pursuing higher management roles—I just enjoy coding too much. Outside of programming, my other passions, even if they're a bit cliché, include traveling, exploring new cuisines, and kite surfing. These activities offer me a refreshing break and inspire creativity in my work.

I'm currently open to new opportunities where I can put my coding skills to good use. If you know of any interesting projects, feel free to Connect with me on Linkedin!
