Who I am
About Me
Hi, I'm Quang Trinh Khac (or just Aleks). I'm an engineer with a genuine curiosity for technology, open source, and the little things that make software work. By day, I build user interfaces with React and modern web tools. By night, I explore how things work under the hood: modding games, reverse engineering, and sharing what I learn along the way.
I studied in the Advanced Education Program (AEP) in Information Systems at Ho Chi Minh City University of Information Technology (UIT), where I found a real passion for learning, both inside and outside the classroom. While my path hasn't been the most traditional, hands-on experience and continuous improvement have shaped my journey.
I'm grateful for the open source community, where I've learned a lot and enjoy giving back when I can. I share modding tools for games, contribute to public projects, and experiment with both web and systems-level code. If you appreciate reliable engineering and a bit of creative problem-solving, I'd be happy to connect.
I enjoy working with teams who care about quality and learning. If you'd like to collaborate or just talk shop, feel free to reach out!

I keep a blog called Ljóss: devlogs, deep dives, and whatever I broke this month.
The Object Already Knows Its Own Name
A bug report from my modding idol grew into RTTI self-heal: mods that re-find their own offsets.

Every Letter in This PDF Is a Drawing
Chromium drew my resume by hand: a PDF with zero font programs. The trigger is one branch in Skia, and pinning font weights does not dodge it.

"use server" Is an Export, Not an Annotation
It does not mean runs on the server. It means every export becomes an HTTP endpoint, and mine handed 31 private repos to a bare curl.
