Selected work

What I'm building now — an AI-agent workflow tool and a digital twin — plus three shipped projects that show the range: two Meta Quest lab simulations and the shader craft that runs through them. Videos load when you press play.

2026 · TOOL · AI AGENTS

Bridge

One desk for me and my AI coding agents. Agents work in real terminal windows; I write the plan with sketches, hand it off in one click, and answer when an agent asks for a decision. Each build comes back with a check sheet to test in the game — what breaks goes straight back to the agent. Hidden git-snapshot checkpoints keep every step reversible. Built solo for my own Unity project.

2026 — PRESENT · DIGITAL TWIN · WEB → VR

Digital Twin Project

An in-progress digital twin platform, built in deliberate phases — shipping on the web first, then scaling the same world up to VR on Meta Quest. One codebase, one Unity project, growing from browser to headset.

2024 — 2025 · VR · EDUCATION

VR Briscoe

A reflux-experiment chemistry simulation for students on Meta Quest. Extended the ObjectiveSystem built for Micropipette, authored the hologram guide shaders, highlight effects, and render-order management across the whole app — then profiled it with Unity Profiler, Frame Debugger, and Meta VSS until it held frame on device.

2024 · VR · EDUCATION

VR Micropipette

Micropipette technique training on Meta Quest. Designed the overall application structure and built the ObjectiveSystem — the tutorial framework every later project inherited. Authored the Water Tilting and Water Wobble shaders, and owned the final optimization pass end to end.

2023 · SHADER · STUDY

Shader Portfolio

A 12-week deep dive into Unity CG / HLSL, re-implemented in Shader Graph. Shaders are the first thing a player feels about a world — this is where the design major and the programmer meet. The background of this page is the same craft, running live in WebGL.

Three disciplines, one developer

Most developers see one side of production. I've shipped from all three chairs — which is why the shaders look right, the systems hold up, and the design intent survives.

Visual Design

university major

Learned how things should look — composition, color, and the graphic instinct that later became shader work.

Game Designer

Hound 13

Learned why games are fun — systems, balance, and data. Built VSTO Excel tooling to make the whole team faster.

Game Programmer

SIMNI Studio

Learned to build it all — VR simulations on Meta Quest, Firebase live ops, and optimization that holds frame on device.

I build how games look — and how they run.
