Patterns we’ve shipped

Battle-tested building blocks, with stack notes and honest guidance on when to reach for each.

Tool-using agent for tier-1 support with hard guardrails on what it can do and a clean handoff to humans when confidence drops.

When to use: Repetitive support workflows (password resets, order status, refunds within policy) where you can enumerate the safe tool set.

Async, queue-backed extraction pipeline for invoices, contracts, and structured forms with human-in-the-loop review.

When to use: High-volume document workflows where you need throughput, audit logs, and graceful failure modes for low-confidence pages.

Production-grade retrieval-augmented generation using AWS Bedrock Knowledge Bases and OpenSearch Serverless.

When to use: Internal Q&A over private documents where data must stay in your AWS account and citations are non-negotiable.
