AI-Native · UI · Product
Ethan Salisbury
Founding Engineer
Ten years shipping product UI — the last two of them AI-native, end-to-end. I led engineering standards across 30+ developers at Plexus, then built the front ends of Synadia Cloud and CodeCargo, working with AI in the loop every day. Open to technical leadership opportunities.

CodeCargo
Founding Engineer · AI-Native IDP
Founding engineer on an AI-native internal developer platform. Architected and shipped it end-to-end — real-time LLM streaming with a Monaco diff-accept UX, an interactive React Flow workflow visualizer with animated dependency edges, a CargoWall security overlay rendered live over workflow nodes, and web gRPC transport. Mentored two engineers on code quality and UX.

About
Hands-on, end-to-end.
Arizona · Remote
I'm happiest owning a product surface end-to-end — from design partnership through architecture, shipping, and iteration. Currently focused on AI-native product UI: both building it and building with it. Based in Arizona, remote-first.
