Web & API penetration testing, red team methodology, and offensive security automation — grounded in 5+ years of hands-on infrastructure & application security practice.
01 // profile
About Me
Security-focused engineer with hands-on experience in web application penetration testing, API security testing, Linux systems, cloud fundamentals, and secure infrastructure practices. Comfortable across the offensive security lifecycle — recon, vulnerability assessment, exploitation attempts against lab & sanctioned targets, and clear-language security reporting — using OWASP-aligned methodology.
Background bridges technical education and applied security: 5+ years designing hands-on cybersecurity labs (Active Directory, Docker, virtualized networks) and training programs, paired with independent security research across PortSwigger, TryHackMe, and Hack The Box. Strong self-driven learner with a builder mindset — combines offensive security knowledge with automation (Python, Bash) and practical software development.
