Software Engineer · Mobile, Web & Game Developer · Athens, Greece CEO & Founder, SepeTech L.P.

I'm a software engineer who builds across mobile, web, and games. I work hands-on every day, from architecture and implementation through release and iteration, across Flutter, React, Angular, .NET, and Unreal Engine 5. I run SepeTech L.P., a Greek software house that ships production-grade software for clients in Greece and abroad.

• Mobile apps in Flutter (iOS + Android), SwiftUI, and native Android (Java)
• Web platforms in React/Next.js and Angular on top of .NET APIs and cloud (Azure, Google Cloud)
• Games in Unreal Engine 5 and C++, targeting both mobile and desktop

Most of the platforms I work on handle sensitive data for K-12 schools, healthcare, and assessment workflows, so security is built in from day one rather than bolted on later.

• HIPAA-aligned handling of protected health information for behavioral and mental-health assessment platforms.
• FERPA-aligned student data flows, role-based access, and parent/guardian consent workflows for K-12 products.
• Architecture, identity, and operational controls mapped to NIST CSF 2.0 (Govern, Identify, Protect, Detect, Respond, Recover).
• Hands-on practices I apply: least-privilege RBAC, tenant isolation, encryption in transit and at rest, secret hygiene, audit trails, dependency review, and hardened input validation on every public endpoint.

• Edumetrisis LLC · K-12 behavioral, SEL, and wellness assessment platforms (BIMAS-3, BASI, CAWS, K-SEP, Mathesis AI) · built to HIPAA, FERPA, and NIST CSF 2.0
• Triaena Business Center · Event management platform, member portal, and international conference websites (ECF25, MWOConf)
• PSTA · iOS/Android apps for goal achievement and mental health first aid (iGrow Goals, iGrow MHFA)
