> STATUS: ONLINE // SLIIT Y1S2 // FULLSTACK DEVELOPER
I am a first-year IT student at SLIIT with a passion for building real, functional systems — from full-stack web applications to hardened server infrastructure. I believe in quality over quantity, and I approach every project with the mindset that if something is worth building, it's worth building properly.
Beyond development, I'm deeply interested in cybersecurity — understanding how systems are attacked so I can defend them better. My infrastructure work includes securing tunnels, monitoring threats, and hardening server configurations. I'm actively pursuing hands-on security knowledge through platforms like TryHackMe and HackTheBox.
When I'm not coding or securing systems, I build open-source projects on GitHub — from Spring Boot backends and IoT systems to animated frontends and event portals. I value loyalty, meaningful relationships, and work that has real impact.

Cybersecurity Roadmap
Blue Team
Monitoring, threat detection, Grafana dashboards, firewall hardening, and incident response. Running Tor relay and security monitoring on live infrastructure.
Red Team
Understanding attack vectors — reconnaissance, scanning, exploitation fundamentals. Active learning on TryHackMe / HackTheBox with Nmap, Metasploit, Wireshark.
Certification Path
Planning CompTIA Security+ and eJPT. Building toward a career where security is embedded in every layer — from application code to network infrastructure.
