LegalAgent

I built the voice and chat assistant inside LegalAgent's React Native application, helping attorneys retrieve case information, summarize documents, and navigate procedural questions in English and Spanish.

Chat runs through the Vercel AI SDK, while voice uses OpenAI's Realtime API for live transcription and speech synthesis. I connected both experiences to retrieval-augmented generation (RAG) and refined the assistant's persona and tool-calling behavior using feedback from attorney sessions.

I also developed an internal administration dashboard with TanStack Start, Microsoft SSO, system prompt management, and document categorization. It gave the team a way to manage the knowledge and behavior behind the assistant without changing application code.
