hey, i’m Neo :)
cybersec student • researcher • startup founder 🇱🇰
Welcome to my digital garden, a living collection of Notes, Writeups, Researches, Things i learn rand experiments from my journey through cybersecurity, research, and building a startup @brainus.lk.
This space isn’t a blog in the traditional sense. It’s a public dump of personal obsidian notes!
what you’ll find here
-
As a CyberSec Undergrad
- CTF writeups
- vulnerability research
- CyberSec Related notes, exploring how things works
-
Thing I Learn
- concepts I’m learning
- tools, commands, and workflows
- Fields around : Computer Science, AI, ML, DevOps & CyberSec
-
Startup Life
- building in public (maybe, idk)
- lessons from shipping (and failing)
- ideas, experiments, and reflections
How to read this
Nothing here is polished.
Notes may be incomplete, messy, or opinionated.
Some pages evolve over time. Some are abandoned halfway through.
That’s intentional. Think of this as browsing someone’s Obsidian vault, not a finished book.
Why?
- to learn better by writing
- to think clearly in public
- to leave a trail for others on the same path
If something here helps you, great.
If something is wrong, even better, it means I’m learning.
