## Target role
Senior Frontend React Engineer | Modern Family Law

## Profile
I’m Chad, a frontend-focused product engineer who builds React and TypeScript products from the interface through the API. My recent work includes React 19, Zustand and schema-defined forms, plus Weft/Warp, my reactive TSX framework and UI toolkit. For Modern Family Law, I bring hands-on experience making complex state, document workflows and AI-assisted features understandable, with privacy and recovery treated as part of the product.

## Curated capabilities
- React, Next.js, TypeScript, TSX, JavaScript, HTML and CSS
- Component architecture, Zustand, derived state and schema-defined forms
- Typed API contracts, tRPC, REST, PostgreSQL and Node.js
- OAuth/OIDC, tenant-aware interfaces, document workflows and audit trails
- AI integration, accessible UI patterns, frontend tests and production operations
