Message

At Travelers, I built agentic AI coding tools on Claude Code and MCP that are used daily by a large engineering organization. I also paired React.js screens with Node.js REST APIs to ship features end to end.

I modernized insurance screens to UI standards and WCAG 2.2 AA, retiring 40 reported usability and accessibility defects at the root. I also rewrote shared React.js and TypeScript components, consolidating four near-duplicate modals into one configurable component.

Earlier, I shipped the first release of DISQO Inc.'s single-page app and built web products across media, education, and news. At Metro Media Associates LLC, I replaced paper enrollment with a responsive system and developed an educational tool adopted by six classrooms.
