Proof of Work
Vercel AI SDK: Unified TypeScript Toolkit for AI Applications
Led the architecture and release of the Vercel AI SDK (ai), providing provider-agnostic streaming abstractions (streamText, streamObject), unified tool calling, and React hooks (useChat, useCompletion).
Streaming protocols must account for varying token delimiter conventions and rate limits across heterogeneous LLM inference providers.
Context: TypeScript, Node.js, Web Streams API, Server-Sent Events (SSE).
View missionv0.dev: Natural Language Generative User Interface Engine
Conceived and deployed v0, a generative UI system that interprets natural language specifications to stream, validate, and preview accessible React, Tailwind CSS, and Lucide component hierarchies.
Generative UI component trees require human audit for state synchronization, accessibility landmarks, and backend API integration.
Context: React Server Components, Next.js, Anthropic Claude & OpenAI foundation models.
