AI Integration Engineer

I help teams design and ship reliable AI features for existing products, from early investigation and architecture through model selection, tool integration, permissions, and implementation.

Full-stack foundations, focused on AWS Bedrock, LLM agents, MCP, TypeScript, and Go.

AI integration

I can join at any stage: clarifying an idea, reviewing architecture, comparing Bedrock models and cost, building MCP or tool integrations, improving agent reliability and permissions, or implementing the feature in an existing TypeScript or Go product.
