At Cornerstone, I diagnose and resolve authentication, integration, and backend issues across an enterprise SSO system and a distributed, multi-tenant SaaS platform. I also validate backend integration points during the unification of two LMS platforms and support AI capability integration.
I built and deployed DocGPT AI, a RAG chatbot that delivers context-aware streaming responses over uploaded documents. Its retrieval pipeline uses BGE embeddings, pgvector semantic search, and Groq LLM, with a FastAPI embedding service integrated into a Spring Boot backend.
