Senior Specialist Cybersecurity @ Etiya

About

I'm a Cybersecurity Specialist and Python Developer with over 4 years of experience in penetration testing, red teaming, and secure software development. I specialize in web and network security, CI/CD pipeline hardening, and Python-based automation, aligning security practices with frameworks like ISO/IEC 27001 and OWASP Top 10. My work spans both offensive security (red teaming, threat modeling, vulnerability assessments) and secure development (Python scripting, API reviews, DevSecOps tooling). I build internal tools to improve security operations, automate testing workflows, and support secure coding practices across engineering teams. I'm passionate about helping companies strengthen their security posture by identifying risks early, automating defenses, and bridging the gap between security and development. 🔑 Key Areas: Penetration Testing · Red Teaming · API Security · Secure Coding · Python · ISO/IEC 27001 · OWASP Top 10 · CI/CD Hardening · Threat Modeling · DevSecOps · Flask · Security Automation
