The full Experience at a glance

Hey there, am Nick. Its 2026, and am currently 24 years. I love tough technical subjects and challenges, of course.

RennexTech is my personal knowledge base for deep, low-level computing documentation, covering the under-documented and undocumented areas of operating systems, programming languages, network protocols, and reverse engineering.

That includes: 

• Programming in C/C++/Python/Golang/Assembly/WinAPI. Those are my favorites. Am not a master at programming with all these difficult languages, currently specializing in python. 

• Networking - I used the TCP/IP illustrated book volume 1 and made my own version of the notes. Same to all the other subjects I have released on my github like Operating Systems by Silbertchatz(under construction), Commandline Scripting, Assembly Language programming and Windows API programming. 

• Reverse engineering and Malware Analysis - Tutorials, tools and methods I discover. This is a future hobby, and its where I will really have to learn the languages I just mentioned above there. Its a hobby because in Kenya, its difficult to land a reverse engineering cybersecurity job if you have no connections, like me. Which is fine. I can start anywhere, and as I upgrade my skills, I will definitely land that job. Its not impossible, but I have accepted it will take time. 

I will document everything to the core. 

This site will have structured notes, diagrams, and explanations derived from deep reading of foundational computer science texts.

The goal is simple, we're here to understand how systems actually work beneath abstraction layers/frameworks, but occassionally we shall dive into the high-level languages like Python and JavaScript, and do web development projects.

Am designing this both as a personal reference and as a learning resource for others wanting to get into cybersecurity, and specifically, reverse engineering of software and hardware. 

All notes are organized by subject and will continue to expand as time goes by. 

You're welcome to this space. Feel free to email me if you want. Am always down to talk!😊Send cool stuff. Ask for another support method? 

The core pages on this site are...

The rest of the pages are going to be released as time goes by... eg Reverse Engineering, Projects, CyberSecurity and the fun stuff I will be exploring in future.
