Top SchoolEfthymios Koktsidis is a backend engineer with nine years of experience building web and full-stack systems, currently focused on Microsoft technologies and .NET. Based in Thessaloniki, Greece, he has progressed from full‑stack roles at RayCom and Onelity to backend specialist positions at Kaizen Gaming and ATCOM, bringing practical production experience across gaming and enterprise projects. He combines disciplined engineering (shaped in part by a stint in the Greek Army) with a pragmatic approach to scalable server-side design and API development. Comfortable across the stack, he favors robust back-end architectures and pragmatic integrations over premature optimization.
