About

Vasileios Laios

I've spent 30 years designing and building software systems — from early enterprise architectures to modern distributed platforms. Over that time I've learned that the best solutions aren't the most complex ones. Clean architecture, clear thinking, and the right tool for the job. That's always been the philosophy. For the past few years I've been going deep on AI Engineering — not the hype, but the actual craft of building systems where AI agents do real work. Workflows that think, pipelines that decide, tools that act. I build these things, I write about them, and I share what actually works in practice. CyberDevTech is where I publish my thinking — on AI agents, software architecture, and the practical side of integrating intelligence into the systems we build every day.
