About Me

I am a cybersecurity enthusiast and developer focused on offensive security and ethical hacking, with a strong interest in Vulnerability Assessment and Penetration Testing. I analyze systems, networks and web applications to identify security weaknesses and understand real-world attack techniques. As a developer, I design and build secure applications. This portfolio itself was developed and secured by me as a web application, reflecting my approach to both development and security. My goal is to grow into a skilled offensive security professional contributing to red team operations while strengthening defenses through realistic attack simulations and continuously expanding my expertise in Windows, Linux, Networking, Active Directory, exploit development and secure web development.
