Lucas Richards Team Lead RSVP Approved

Founder at Flambé
Architected and built the full-stack system end-to-end. Designed the React Native mobile app with the 5-phase state machine, CallKit integration via react-native-callkeep, and the SessionScreen with real-time tips overlay. Built the Next.js backend including all API routes — Tavus pre-warming and conversation caching, the webhook event processor that pipes therapist utterances to Claude Sonnet 4 for real-time tip generation, the CopilotKit runtime with Anthropic adapter, and the Redis caching layer with graceful degradation. Developed the session memory system that injects previous session summaries into the Tavus therapist prompt. Configured deployment on Google Cloud Run and managed environment orchestration across Tavus, Anthropic, and Redis services.

Principal Engineer at OneEleven
Designed and implemented the Tavus therapist persona and conversational context — crafted the system prompt that defines Serenity's personality, tone, and therapeutic approach (CBT, attachment theory, founder-specific framing). Built the custom greeting flow and session summary saving pipeline via the Tavus webhook integration. - Configured the Tavus replica and persona settings, and contributed to the webhook callback URL setup for production deployment on Cloud Run.
