Who I am

About Me

I am an aspiring cybersecurity professional with a strong interest in protecting systems, networks, and data from modern security threats. I am continuously learning key areas such as network security, threat detection, and secure system practices, while building a solid foundation in cybersecurity principles.

Alongside cybersecurity, I am developing my skills in backend development, focusing on creating secure, efficient, and scalable server-side applications. I enjoy working with technologies that help manage data, handle authentication, and improve system performance.

Beyond code, I'm a President Scout and Senior Prefect(2022) — a leader who thrives in team environments and brings discipline and structure to every project.I am passionate about learning, improving my technical skills, and growing into a professional who can contribute to building secure and reliable digital systems.
