About me


Carlos Baraza

Chief Technology Officer

Hello! I'm Carlos, and I am one of those people who learnt to code as a kid. Writing Software has been my passion since. As a Software Engineer with 10+ years of experience, I commit to bringing technical knowledge (hopefully) and success (hopefully) to every project and organization I work with.

Currently, I am the CTO at inpractise.com. Previously worked at Bloomberg, Expedia, DAZN and others.

I love web development. I use modern but stable technologies, and I keep my knowledge updated. Playing music is my way to relax.

If you want to connect, I'm available in a myriad ways, like Twitter (@carlosbaraza). And if you want to hire me, please keep reading my resume :).
