I'm Andrew Rainsberger, a game developer and technical tools builder in Dixon, Missouri. I work where gameplay, technical art, and practical software overlap: playable 3D systems, authored environments, Blender/Python pipelines, and desktop tools that make difficult work easier to repeat.

What matters to me:

• Feel first. Movement, cameras, controls, feedback, and readable player choices make a system worth using.
• Tools are part of the product. Better authoring and validation workflows produce better worlds.
• Show the evidence. I value runnable builds, real captures, focused tests, and honest limits over polished claims.

A playable underwater survival world built across the full pipeline. I worked on player movement, feeding, abilities, camera states, HUD, lobby flow, and simulation systems, then connected authored Blender terrain, coral, landmarks, and export data to the Three.js runtime.

A Blender 4.3+ add-on with a production QuadriFlow path and an experimental standalone quad-dominant engine. It preserves the things artists care about—shape, features, materials, and UVs—while reporting useful quality metrics instead of hiding the result behind one button.

• Deterministic remeshing, projection, cleanup, and voxel-repair fallback
• UV and material transfer with measurable topology/quality reports
• Standalone OBJ CLI plus Blender headless smoke coverage
• MIT licensed and validated against Blender 4.5 LTS

Repository and installation →

A Windows command center for guided screen observation and isolated browser automation. The interesting problem is not just making automation work—it is making every step visible, stoppable, and appropriately gated.

• Observe-only live screen guidance
• Isolated Playwright browser with approval gates
• Visible plans, target overlays, pause/stop controls, and verification loops
• Local, loopback-only bridge with per-session authorization

Repository, releases, and safety model →

• Deltawave — a native C++20 music visualizer with live WASAPI analysis, procedural 2D/3D scenes, adaptive audio profiles, deterministic export, and performance telemetry.
• Linear Drive — a first-person survival-horror driving game in C++/raylib with a physical, diegetic cockpit and reactive road hazards. View the cockpit case study.
• MeasuringStick — a lightweight C# system-tray utility for pixel measurement and screenshot capture on Windows.
• A3DCO, ObservableKeymap, and Blender Alignment Suite — small Blender add-ons built around everyday modeling friction.
• Claude Citizen — Solar Atlas contribution — 10 authored commits in a merged upstream PR covering navigation, pointer-lock safety, orbit selection, and visual polish. Read the contribution case study.

1. Find the player or artist problem. Start from the moment that feels slow, unclear, fragile, or unconvincing.

2. Build a complete vertical slice. Connect the interaction, visuals, data, and tooling early enough to expose the real problems.

3. Test the result where it lives. Browser playtests, Blender headless runs, geometry assertions, screenshots, builds, and performance checks all count as part of the work.

4. Keep the limits visible. Experimental work stays labeled experimental. Private work gets a public case study, not a pretend-open repository.

Before software, I completed electrical pre-apprenticeship training and served a season on a wildland firefighting crew through Job Corps. That background still shapes how I work: respect constraints, communicate clearly, learn the system, check the tools, and stay useful when conditions change.

I'm currently focused on junior game development, tools development, and technical-art-adjacent roles where I can keep bridging creative intent and engineering execution.
