TanStack Start

TanStack Query

Chosen architecture

I define the platform's frontend architecture. I selected TanStack Start, with TanStack Query handling server state, caching, and loading and error states — over a client-state library, because the product is API-driven. I also contribute to the Node.js backend, inside a monorepo that houses the product's proprietary AI layer. This site runs on the same choice.
