n4ctbyte/ctf-portfolio ? reverse-engineered prompt

Build me a clean, modern portfolio site for a CTF player so I can show off my profile, challenge writeups, skills, achievements, and contact info in one place.

I want it to feel a little cyber themed without being hard to use. Make it responsive and polished, with a nice landing section, an about area, a section for CTF categories and tools I use, and a gallery or list of solved challenges with short summaries. It should be easy to browse writeups by type, like web, crypto, reverse, or pwn, and each entry should have room for a title, event name, date, tags, difficulty, and links if I have them.

Please also include a simple way to manage or load the portfolio content, and a contact section or form if that fits. Keep the code organized and make the app feel complete, not just a mockup. If you need to, look up current docs online and fill in sensible details.
