LLM Integrations
AI features inside real products.
The work
Putting a model inside a product is an engineering problem: structured output, tool calling, retries, evals, latency and cost. I treat prompts like code and outputs like untrusted input.
From copilots and smart replies to document understanding and generation pipelines.
What I deliver
- Copilots and AI features embedded in existing apps
- Structured extraction from documents, email and the web
- Content and ad generation pipelines with brand guardrails
- Model selection, evals and cost control
