Built and deployed two independent AI systems. MeetMind — an agentic meeting assistant using a 6-node LangGraph reasoning chain with OpenAI Whisper, solving context-loss in 60+ minute recordings. Proposal AI — an internal agent using ChromaDB memory and few-shot prompting to generate personalized proposals. Both deployed on DigitalOcean with FastAPI, JWT auth, and Docker.
