Hello, I’m Catalin.

Technical Advisor, Software Engineer and Product Developer from Germany.

My tech journey began around 2005 with a fascination for cybersecurity at the age of 13 when ICQ was the thing, and it quickly grew into a passion for coding and development.

I studied computer science and even worked in a bootstrapped startup, getting to know the lean culture firsthand and all about being efficient with resources and creating MVP's that focus on UX and Business. I've been working as an independent software engineer since 2018.
