OrchestrAI

Online shopping is spread across dozens of retailer sites with inconsistent stock data and repetitive checkout forms, so comparing and buying one item can take ten or more manual steps.

Full-stack engineer

• Chained structured tool calls to query retailer catalogues, harmonise specs and rank items by price-to-spec ratio.
• Kept the basket in an immutable client store, so the model could never hallucinate items or quantities.
• Queried retailers concurrently with a 1.8s timeout, and validated every upstream payload with Zod.
