Capstone — design RAG for support tickets
A realistic system design exercise. Pick chunking, retrieval, eval, and ops choices.
The brief
Your SaaS company has:
- 10,000 internal docs (Markdown files in a wiki)
- 50,000 historical support tickets (each has problem, resolution, tags)
- ~500 support requests per day
- A small support team that wants AI-suggested replies grounded in past tickets and docs
Design the RAG. Make engineering tradeoffs.
