What I'm looking for

I’m looking for remote full-time or contract work (W-2 or 1099), bringing my experience building enterprise platforms and front ends to a team that needs design and engineering support.

At Halliburton, I own the experience layer for two enterprise platforms built on an agentic software development lifecycle. I built the front end and UX proof of concept replacing a company-wide time-billing tool used by 30,000+ employees, projected to save about $4M a year.

I also designed and built the UI/UX for an enterprise data-product marketplace, taking it from Figma through production React and Next.js; it shipped to worldwide internal production. I create design systems and workflows for agent-built software, with human review and design-fidelity gates.

Before Halliburton, I spent 12 years at Henry Schein One. I architected company-wide design systems, maintained accessibility standards across product lines, and built and maintained AWS WordPress multisite infrastructure for 500+ dental and medical practices.

I’ve been building for the web since 1999, from design tokens through production interfaces. I’m open to remote full-time or contract roles, W-2 or 1099.
