A glimpse into my journey
Paulos Berihun
I am a 17-year-old software developer and cybersecurity engineer with a strong focus on building secure, production-ready systems. I believe security isn't an add-on — it's a fundamental part of software development.
I specialize in secure authentication systems, role-based access control (RBAC), and infrastructure-aware development. My approach combines clean code principles with security best practices to create resilient applications.
As Founder of GashaX Security, I'm dedicated to building next-generation security frameworks and raising awareness about secure software development practices. We help organizations build security-first applications and train the next generation of cybersecurity talent.
