Christos Sotiriou

Principal software engineer & architect

Software.
Simplified.

For 18+ years I’ve built software for people, from iPhone apps to platforms serving four million customers.

I remove friction and complexity. I combine human judgment, AI agents and hands-on engineering to build systems that humans care about.

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