About

Hi, I’m Tony Gaitatzis, a senior software engineer with over 15 years of experience specializing in machine learning and full-stack development.

I enjoy collaborating across teams and leading innovative projects, whether that’s in enterprise environments or hands-on product development. Writing technical books and sharing knowledge in the developer community is also something I greatly value. I’m always eager to explore new technologies and push the boundaries of what’s possible with software engineering.
