About
The short version.
Chartered Engineer with 10+ years inside the nuclear sector, working in secure regulated environments. I work across nuclear engineering, energy systems, business and AI, turning complex plant constraints into safe, maintainable, compliant engineering solutions.
My background spans plant-facing design, high-hazard system ownership, technical assurance, operational readiness and multi-million-pound project delivery. I combine an MEng, two MSc degrees, a PhD and an MBA in Business Economics & Artificial Intelligence with practical AI capability, broad professional CPD and international innovation recognition.
I hold five granted patents and nine research works indexed on ORCID, Zenodo and Google Scholar, and represented Greece at the World Robot Olympiad, from Yokohama to Abu Dhabi. My research focuses on hydrogen technologies and nuclear energy as enablers of the low-carbon transition.

Adopted by the Greek State
Three years after I exited PosoKanei.gr, the Greek state adopted the same model — and the same name — for its national price-monitoring platform.
A real-time supermarket price-comparison engine and the consumer community of thousands that grew around it: every deal user-submitted and community-verified, no paid placements. The national platform now feeds the Independent Authority for Market Control and Consumer Protection.
