Enterprise Employee Super App

Built the middleware layer connecting Oracle HR, SharePoint, and a locally-hosted AI Assistant (Ollama LLM) into a single enterprise employee platform. Solved authentication across three separate systems, mapped HR data into a unified data model, and implemented retry/error-handling logic for production use. Delivered as part of a three-track build: ASP.NET Core 8 backend, React/React Native frontend, and the AI/RAG pipeline.
