End-to-end use cases.
Working code for the patterns customers ask about most. Copy, paste, ship.
Code review bot
Build a bot that reviews pull requests using Claude Sonnet, with tool calling to read repo files and post inline comments. Includes prompt template, error handling, and webhook integration.
Streaming chat UI
Next.js + React chat interface that streams tokens with sub-second TTFT. SSE parsing, cancellation, mid-stream error handling, and inline guardrail status display.
Batch document analysis
Process 10,000 PDFs overnight at 50% the realtime cost. Async batch enqueue + poll loop, structured extraction with JSON mode, progress tracking, failure recovery.
RAG with caching
Retrieval-augmented chat backend. Embed once, retrieve fast, then chat — with the stable system prompt cached at 90% off so high-volume RAG stays cheap.
Cost-optimized routing
Route easy requests to a budget model, hard requests to premium. Two patterns: classifier-first and confidence-based escalation. 80%+ savings vs naive routing.
