WarpedBed
A storefront for 3D printed tabletop gaming accessories, built from an empty repo. Product catalog, checkout, order pipeline, and the fulfillment tooling behind it. I designed a multimodal support chatbot for it using tiered model routing and prompt caching to keep per-conversation cost low.

DeckPress
