Architecting
The Future
Hi, I'm Thomas Kantartzis. A CTO & Full-Stack Engineer who turns complex legacy systems into sleek, scalable cloud architectures.
About Me
I don't just write code; I build businesses. My career has been defined by a dual focus: high-level strategy and deep-dive engineering.
Whether it's migrating a 20-year-old database without downtime or negotiating client contracts, I bring a "can-do" attitude to every problem. I believe technology should serve the business, not the other way around.
