AI systems.
Product engineering.

I build and maintain software, including a browser-based creation platform with paying users. Here's the architecture, applied AI work, and engineering behind what I ship.

SlayA browser-based authoring
and compilation platform.

Create characters for Slay the Spire 2 without setting up a C# development environment. A visual editor turns cards, effects, and character designs into source code, then builds a downloadable mod.

I built and maintain the product across the editor, code generation, build service, and cloud features. Its earlier AI generation pipeline is documented separately in the case study.

Selected work

Experiments & collaborations

In development

Mistborn VR

A Mistborn-inspired VR prototype for Quest 3. Physics-driven metal pushing and pulling, built with Godot, OpenXR, and Jolt. An ongoing exploration of movement and interaction in VR.

Archived experiment

Type Anything

A word-driven physics game exploring constrained AI generation: the model selects from a defined component library. The public browser build uses cached content. A useful lesson in the gap between a valid level and an enjoyable one.

Prototype collaboration

Manufacturing assistant

Contributed to another developer's knowledge-assistant prototype for manufacturing documentation. This was collaborative prototype work; it is not presented as a launched customer deployment.
