SeanGPT is a retrieval interface over my Obsidian vault of college notes — the same notebook linked from the homepage. The vault syncs from GitHub into a vector database on every push, so the model always answers against my latest notes.
- Built a RAG pipeline (FastAPI + LangChain) that ingests the Obsidian vault into a ChromaDB vector store on each push, enabling natural-language Q&A over my notes with OpenAI embeddings and GPT-4 / Claude.
- Dockerized and deployed to AWS ECS with Route 53 via CI/CD, cutting deployment time by 70% and query costs by 80%.
