01. About Me

Who I am. About Charlen Baloukjy

Hello! I'm Charlen Baloukjy.

I am a Computer Science graduate from Kutztown University of Pennsylvania working as a freelance cybersecurity analyst, penetration tester, and full-stack software & web developer. My technical foundation spans building modern web applications, designing scalable backend systems, socket programming, network analysis, and secure code architecture. I am passionate about crafting clean, efficient code, building responsive user interfaces, and ensuring client applications are built securely from the ground up.

Whether delivering custom client websites, performing web application security audits, or developing bespoke software tools, I bridge the gap between software engineering and cybersecurity. I offer freelance and contract services designed to scale your business, harden your digital infrastructure, and protect your web applications against modern threat vectors.
