Welcome

hey, i’m Neo

cybersec student, researcher, startup founder 🇱🇰

Welcome to my digital garden - a living collection of notes, writeups, research, and experiments from my journey through cybersecurity, building a startup @brainus.lk, and learning in public.

This isn’t a blog. It’s a public dump of personal Obsidian notes.

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.
