Building @Xstartup / Studying at 1337 |
| Hobbies |
Music / Reading / Writing |
I'm currently a student at 1337 and a software engineer. I'm also building my own startup on the side.
I spend most of my time learning about low-level systems, math, cryptography and advanced machine intelligence.
I like to build tools for my own good and some of it is public to use by others, you can check the projects part.
In my free time i do write and share my thoughts on substack, you can reach it through the link =>
[MY SUBSTACK]
. my writings covers different topics include: linux, math, cryptography, computer stuff ...

Learning
Public repositories I use to study and take notes -- networking, memory, math, and more.
Curriculum
Projects built while learning -- practice, exercises, and things built to understand something deeper.
Lib
A personal library -- PDFs, papers, and resources worth keeping. Mine and others.
Media
A personal library -- Pictures, Videos ...etc, for me and the events i was in.

[ 04 -- LEARNING ]
These are learning resources I built for myself while studying. I write them down,
structure them, and make them public so others can read and benefit from them too.
Every resource here started as personal notes and turned into something shareable.
