I've sat across the table from the buyer and behind the terminal. I build systems with both sides in mind.

About

Meletios Flevarakis at a Debate House event
Debate House event, Athens

I build, break, and fix things for a living.

Started in presales and solutions architecture at HPE, where I spent 6+ years designing infrastructure for enterprise clients. That foundation gave me something most engineers don't have — a holistic view of what the market actually needs, so I build what matters, not just what's technically interesting.

Now I'm at Hack The Box, working as a Systems Engineer — closer to the metal, closer to the security side of things. On the side, I lead technology at Debate House, a social non-profit where I use digital tools to scale public dialogue between citizens and political figures across Greece.

Business Acumen

6+ years in presales and solutions architecture. I understand what the market needs before writing a single line of code.

Technical Depth

Systems engineering, infrastructure, and cybersecurity. I build things that scale, stay secure, and don't break at 3am.
