Christos Sotiriou

Engineering leader & architect

Complexity.
Simplified.

I’ve built software and the teams behind it, from iPhone apps to platforms serving four million customers.

Most complexity doesn’t live in the code. It lives in the handovers, approvals and dependencies between teams. I remove it as an architect, a hands-on engineer and a leader of engineering teams, using AI agents where they genuinely help.

I also write about software and speak at events like Red Hat Summit, DTW Ignite and Devoxx.
