I'm a computer engineer (Class of 2026) who builds backend systems and thinks about security from the first line of code. I work mostly with C#, Node.js and Go, design projects around layered architecture, SOLID and OOP, and I like problems where networking, cryptography and AI meet.

My graduation project, Cipher, an end-to-end encrypted peer-to-peer messaging app, was published in the International Journal of Advanced Networking and Applications.

  ◆ Looking for — junior backend / software engineering roles, open to AI-adjacent positions
  ◆ Interned at — Çetin Group (ESP32 firmware, IT infrastructure) · Atia Software (full-stack, PHP & MySQL)
  ◆ Building — 16 small, well-tested apps in Python, JavaScript, Java and C++, currently a Java/JavaFX banking app; all of them are on my portfolio
