Senior🎓
Top School𓋹 Hatzis is a pragmatic full-stack engineer and research-trained IT leader based in Athens, combining over a decade of hands-on software engineering with a 30+-year strategic background in academic research and health informatics. He designs and operates resilient cloud-native systems, real-time data pipelines and microservices—recently architecting a marathon resource-management platform that handled live GPS, weather and medical telemetry.

A published researcher with a PhD in Speech Technology and an MSc in AI, he blends formal methods and semantic/knowledge-graph thinking into practical analytics and visualisation tools. Unusually, his profile spans both clinical systems engineering and creative musical training (classical piano and Byzantine chant), reflecting a discipline for precision and pattern recognition that informs his software design.
