I like building AI agents around messy human workflows. Most of my work starts with scattered docs, sales calls, spreadsheets, or operational chaos. I turn that into full-stack software, automations, and agent workflows that help people get work done with more clarity.

Currently building with AI to learn and explore what AI-native work actually looks like.
