The person behind SepeTech
About me
I'm George Sepetadelis, 20 years old, CEO and founder of SepeTech, based in Athens, Greece. I started shipping software in 2019 and never stopped: native and cross-platform mobile apps with Flutter, Java, and SwiftUI, games in Unreal Engine 5, and web platforms with React, Angular, and .NET. Today I run SepeTech, where we build scalable and secure digital experiences for clients, with the same obsession I had on day one.
"Good luck finding someone more hard-working than me."

The Beginning
Decided to bring my ideas to life and started developing apps with Android Studio on a 2GB RAM laptop/toaster. Despite the limitations, my passion for mobile development and programming grew. The rest is history.
