Coffre
liveA password manager focused on authentication, cryptographic boundaries, and what a vault should actually trust.
Built because I wanted to understand how keys, sessions, OTPs, and encrypted data fit together beyond a diagram.

fahisxd.
Cybersecurity learner, builder, and creator of SoyezSecurise.
I build security tools, break things to understand them, and document what I learn.
01 / selected work
Projects built to answer questions.
Not polished case studies. These are systems I am building, testing, getting wrong, and rebuilding.
Neuris / v0id
liveAn experimental AI input firewall that classifies XSS, SQL injection, path traversal, command injection, and safe input.
The model is not production-ready. The useful part right now is understanding exactly where it gets confused.
Ayano
research toolA CLI that turns a CVE into a useful starting point for vulnerability research.
It collects the context I usually need—NVD data, proof-of-concept searches, summaries, and research trails.
02 / field notes
Things worth writing down.
03 / about
I learn by making the problem concrete.
I’m Fahis Shehandi, known online as fahisxd. I’m a student learning cybersecurity through projects, CTFs, and a lot of experimentation.
I’m especially interested in web security, Linux, backend systems, cryptography, and the point where AI meets security. Most projects start because I ask “what if I built this myself?” and then discover five technologies I did not know existed.
