Architected a low-latency, voice agent using Python (aiohttp) and Azure AI Services (Speech/GPT-4o), optimizing client-side audio with a custom JavaScript Audio Worklet and implementing barge-in interruption for sub-second, natural responsiveness. Built a custom Agentic Workflow (MCP-based) and Retrieval-Augmented Generation (RAG) engine leveraging Azure OpenAI Embeddings to autonomously execute complex reasoning, query USDA policies, and provide accurate, citation-backed answers. Engineered a hands-free PDF Form Filling system that dynamically inspects schemas (using pypdf) to map conversational data into applications in real-time, auto-generating and emailing completed forms without manual input. Deployed the scalable, containerized application to Azure Container Apps using Docker multi-stage builds, ensuring secure API key management and robust production infrastructure.
