I build production AI systems and full-stack products—from realtime voice agents to the infrastructure that keeps them running. I like the part where product thinking, difficult engineering, and real operations meet.

The AI coworker for trades and local businesses. Griffi receives calls and messages, connects them with business context, and prepares appointments, quotes, invoices, and follow-up. The consequential steps stay visible, reviewable, and under human control. I’m building the product end to end: direction, UX, multi-tenant platform, realtime voice, AI orchestration, infrastructure, security, and the release system. Meet Griffi →

• AI systems — conversational AI, retrieval, tool use, evaluation, guardrails, and realtime voice designed around useful behavior, not a model demo.
• Product engineering — interface, API, data model, and business workflow shaped together, turning ambiguous ideas into coherent products.
• Production operations — containers, infrastructure, observability, security, backups, and guarded releases as part of the product, not an afterthought.

Most of the n3tz code is private because it runs a real product. The n3tz site shows the outcome; my portfolio goes deeper into the work behind it.
