Build me a polished GitHub profile README that looks like a cybersecurity themed personal landing page.

I want it to feel like a purple team and security focused profile, with a clean centered header, a terminal style hero image, and sections for my skills, tools, and social links. Include the kinds of things a security person would want to show, like Linux, Python, C, SQLite, React, FastAPI, Bash, and common security tools such as Nmap, Wireshark, Burp Suite, Metasploit, Shodan, Zeek, Suricata, Hashcat, and Gobuster.

Make it look modern and visually appealing, with icons and logos, but keep it simple enough that it works well as a README on GitHub. Use the assets folder where needed and make sure the layout renders nicely in markdown. If any current badge or icon links need updating, look up the latest docs online first.
