Executive statement
I am a Senior Product Designer & Design Engineer with 12+ years of experience architecting AI-driven digital products, currently building production AI features at Anthropic (the company behind Claude). I operate as a rare hybrid: design leadership plus full-stack engineering, proficient in React, TypeScript, Next.js, and modern AI-assisted development, with deep expertise integrating LLMs (Claude, OpenAI) into production agentic systems. As an independent forward-deployed AI engineer, I have architected and shipped multi-agent platforms (Omnira: an orchestrator plus five specialist agents coordinating 110+ tools across chat and voice for service businesses), AI cost-observability SDKs spanning five major LLM providers, and EU AI Act compliance tooling. At Microsoft I architected AI-powered search experiences serving 100M+ users and built the framework used to integrate ML features across 8 product lines. I take on fractional CTO and AI-technology-lead engagements for founders and SMBs who need someone who can define the technical architecture, ship the first production version personally, and then hand off a system their team can maintain — full lifecycle from discovery through deployment and iteration.
Leadership scope
Led product design and front-end engineering for AI agent products at Anthropic serving millions of users; as an independent forward-deployed AI engineer I own full technical architecture and delivery end-to-end (discovery through production) for founder/SMB engagements without a supporting team.
