c0ffeeOverdose

Just a normal person who loves Cyber Security.

Computer Science student from Thailand, CTF player, and web exploitation enthusiast. I’m also interested in red teaming, though I’m still learning to trust my own skill. Some days I know I’m capable, some days I feel powerless, but I keep building quietly and patiently.

Astro blog deployment

Fuwari on Cloudflare

A Cloudflare Pages adaptation of the Fuwari Astro blog template, keeping deployment friction low while staying close to upstream.

About

A normal person around computers.

I'm a Computer Science student from Thailand, interested in CTFs, web exploitation, and bug chains that feel close to real systems.

I do not have the most structured learning path, but I keep picking things up, breaking them apart, and slowly connecting the pieces.

I'm not always confident in what I know, but solving something after being stuck for hours still makes me want to keep going.

The name says coffee, but the actual fuel is usually an energy drink.
