Developer • modder • performance tinkerer • psychology nerd • chronic profiler
I build, mod, profile, and occasionally reverse-engineer things that interest me. Most of the trail leads through games, rendering, developer tooling, AI, and psychology.
I like systems with knobs, metrics, edge cases, and enough complexity to make a normal person close the tab.
Current projects
Things I’m actually building
Mostly mods, diagnostics, rendering experiments, developer tools, and whatever technical problem was rude enough to become interesting.
Captain of Industry modding & diagnostics
TajsCOI
QoL tweaks, profiling helpers, pathfinding diagnostics, and performance experiments for Captain of Industry. Currently the best place to observe me turning one suspicious stutter into an investigation.
More projects
Other active experiments
Smaller cards, because not every repository needs a monument.
Graphics overhaul experiments
TajsGraph
Rendering obsession packaged as a project: visual tuning, better defaults, performance trade-offs, and a lot of settings archaeology.
Upload Labs QoL mod
TajsMod
A fairly substantial quality-of-life and UI mod for Upload Labs, with tooling, interface changes, configuration, and optional gameplay tweaks.
Unreal Engine INI/CVar tooling
UEiniLab
Tooling for exploring and understanding Unreal Engine configuration variables without manually spelunking through endless INI files.
Constraint-heavy word solver
AnagramSolver
A Python solver for increasingly unreasonable anagram puzzles, with required words, word-count constraints, ranking, and assorted brute-force containment measures.
Personal LifeOS experiment
TajsOS
A second-brain-style experiment around tasks, project context, personal data, and the recurring human problem of forgetting what the plan was.
Recurring interests
Rabbit holes with suspicious persistence
Psychology & mind systems
Attention, behavior, measurement, identity, motivation, and the weird control panels people carry in their heads.
Game dev, modding & reverse engineering
Finding out how a system behaves, where it hurts, and whether a mod can make the whole thing less annoying.
Performance & rendering
Profilers, frame time, pathfinding, VRAM, lighting, CVars, and the eternal question: what exactly is choking now?
AI tooling & automation
Coding agents, workflows, MCP-shaped experiments, and using machines to reduce the ceremonial parts of building things.
Tools & digital systems
Personal dashboards, developer utilities, second-brain experiments, and other attempts to keep context findable.
Input Queue
Current rabbit holes
The subjects currently consuming tabs, profiler captures, notes, or all three. Some become projects. Others become suspiciously specific opinions.
- Game pathfinding, simulation bottlenecks, and profiling
- Unreal Engine rendering, CVars, and editor tooling
- Coding agents, AI workflows, and automation
- Psychometrics, attention, and behavior loops
- Mod architecture, QoL design, and reverse engineering
