What I build

AI that ships to production and does real work: features your customers use and agents that run your operations.

AI Product Features
Chat, assistants, and generation built into your product with Claude and other frontier models. Designed for production from day one: evals, guardrails, and cost control included.
Agentic Software Development
Autonomous agents that do real work: coding agents, scheduled routines, and multi-agent pipelines built on Claude Code, the Claude Agent SDK, and MCP.
Fractional Lead Engineering
Senior fullstack leadership by the hour: architecture, hands-on shipping, code review, and mentoring your team. Next.js, Node, Python, PostgreSQL.
E-commerce & Platform Integration
Shopify, Webflow, payments, and third-party APIs wired together cleanly. Checkout flows and the integrations that actually move revenue.
