The Brief
What you'll do, and what you'll demonstrate.
Pick the production approximate-nearest-neighbor store for a code-search workload by benchmarking Chroma, Qdrant, and Weaviate on recall, latency, RAM, and build time at the same operating point.
This is not a data exercise. It is the work an analyst does when stakeholders need answers from messy data. That distinction matters to every hiring manager who has seen candidates describe statistical methods and none who have extracted insight from messy, real-world data.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Understand HNSW parameters (M, ef_construction, ef_search) and how they trade quality for latency
- Design a fair vector-store benchmark at matched recall
- Project capacity from a 5 M-vector measurement to a 200 M-vector production target
- Defend an infrastructure recommendation to engineering leadership in writing
