01
Typed, virtualized interfaces
A data grid that stays fast on dense screens, with types that make a wrong column key a compile error.
G00 Engineering
The architecture holds it together.
The stack as a node graph, then the six things it is good at, each with the builds that prove it. Vitest runs in 15 of these builds and Playwright in 14.
- Tool calls and agent loops
- Vision with structured output
- Consent before data leaves
- Supabase Postgres
- Row-Level Security
- Edge Functions
- Server-side checks
- Checkout and payouts domain
- Human payment attestation
- Resend email
- Three.js and shaders
- Motion and Lenis
- Code-only visuals
- TanStack Query
- Zod at the edges
- Typed domain packages
- React 19
- TypeScript
- Next.js App Router
- Accessible components
- Vitest
- Playwright journeys
- AI evals
- Strict TypeScript
- Live on the web
- Android-first apps
- Docs and source delivery
G01 Competencies
Six things, with receipts.
Each one links to the builds whose code shows it. Hover a card to square up its model.
02
Component systems
Headless, accessible components with one metadata source for docs, examples and a public registry.
03
Data with clear ownership
Supabase with Row-Level Security, Edge Functions, and apps that share a project without touching each other's tables.
05
Money with a person in the loop
Checkout, reservations and payouts as domain logic, and payments confirmed by a human before anything is baked or shipped.
06
3D that respects the device
Scenes drawn in code that load on demand, pause off screen and fall back to a still frame.
G02 What every build gets
Hand it over, not patch it up.
Whatever the product, the same four habits come with it, so the next developer can pick it up on day one.
- 01Written downA plan, a design system and a short guide live in the repository, so context never lives only in someone's head.
- 02Typed at the edgesStrict TypeScript, with schemas validating anything that crosses a boundary: forms, APIs, payments and AI output.
- 03Tested like a userUnit tests for the logic, browser journeys for the flows that matter, and evals wherever a model is involved.
- 04Reviewed by a personEvery change is read, and anything that moves money or ships to users waits for a human to approve it.
