QuadraJ
I make games, build websites, and document the work in writing.
Current work includes the simulation game LIQUIDATED, the QuadraJ website and Notes, and a web archive for Yangil High School's swallow survey. I also write about software, cultural industries, companies, and capital allocation when they connect to those projects.
What QuadraJ does
A place for work I make and subjects I study.
I design the rules and interface of LIQUIDATED, organize published projects on this website, and use Notes to record decisions from development and research into companies and cultural industries.
The subjects vary, but knowledge from one project often becomes useful in the next. QuadraJ is the name I use to keep that work and research in one place.

Game development under PastelJ Studio and company analysis under Capital / Research are already active. The other names organize longer-term areas I may work in later.
Future interest
QuadraJ Software
Software and web products that solve practical problems for creators and users.
- Current
- The current work is this website, along with small tool ideas and software experiments.
- Direction
- I want to build software that helps creators make and manage their work.
Active work
PastelJ Studio
The name used for LIQUIDATED and other game and visual projects.
- Current
- The active work is independent game development, beginning with LIQUIDATED.
- Direction
- I want later games to keep developing their characters, images, and worlds beyond a single release.
Future interest
QuadraJ Media / Culture
An area of interest covering media, intellectual property, music, video, and creator networks.
- Current
- The current work consists of cultural-industry analysis and project ideas recorded in Notes.
- Direction
- I want to try producing and distributing original content with other creators.
Active research
QuadraJ Capital / Research
Research into companies, industry structure, investment, and capital allocation.
- Current
- Company and industry analysis is currently published in Notes.
- Direction
- For now, the focus remains research and writing; any capital-related activity would require the proper legal and operating foundation.
Long-term idea
QuadraJ Fellowship / Foundation
A long-term idea for connecting creators, entrepreneurs, researchers, and investors.
- Current
- This is currently an idea, not an active organization or program.
- Direction
- After gaining enough project experience and resources, I want to examine practical ways to support creative work and entrepreneurship.
