About

Hi, I’m Reinon.

Computer Science and Technology, junior year.

Someone who loves tinkering and wants to try everything. Rather than just knowing how to use a tool, I want to understand how it actually works under the hood.

What I’m tinkering with

My interests are all over the place, but they roughly fall into a few areas:

Linux: A heavy Arch Linux user. I like starting from a fresh install and gradually shaping the environment into exactly what I want — window manager, terminal, shell, editor, all of it configured by hand before it feels right. Honestly, sometimes I’ll spend a whole day on a single config detail for basically zero productivity gain, but I just can’t stop.

Low-level & security: Learning C and embedded systems, and playing CTFs, mainly PWN. I find it genuinely interesting to understand how registers work, how stack frames are laid out, and how a vulnerability actually comes to be. Compared to writing business logic at the application layer, I’d rather dig deeper.

Embedded / smart car: I’ve worked with microcontrollers, sensor data acquisition, and electromagnetic line following. A simple if-else in code can completely fail on real hardware because of signal jitter. Debugging means thinking about the program, the signal, and the physical behavior all at once — painful, but addictive.

Things I’ve built

QIQI: A desktop assistant I wrote myself. It started as just something fun to build, and later used Python + PySide + QML. Along the way I discovered that a “usable product” and “working code” are two completely different things — interaction, experience, details, all of it full of pitfalls.

The Echo Splitter: A game project where I handled all the level design and also worked on the development of levels two and three. The core idea was to tie English vocabulary to scene interactions and puzzle-solving, so players understand a word through actions and observation rather than rote memorization. It turned out to be a lot of fun — the overlap between game design and programming is much bigger than I imagined.

Smart car project: The first time I experienced code actually driving motors and affecting physical movement in the real world. The mindset for writing software and doing hardware are very different, and being forced to switch between the two taught me a lot.
