Summary

I'm a product designer with six years in UX/UI who doesn't stop at the handoff: I build and ship what I design, taking signed-off specs to production with AI-assisted development. Too many good ideas die between the spec and the shipped product, so I take mine all the way. I founded and shipped two products solo, owning roadmap, prioritization, monetization, and go-to-market, with Junto live in the App Store across 30+ metros and 140+ venues. On contract teams I've cut a 750-page site refresh from an estimated 8 months to 2.5, shipped into a platform used by 10,000+ educators, and mentored a team of 4 designers.

Experience

FairSquare

  • Owned product requirements for the NF broker portal end to end, writing Given/When/Then acceptance criteria for every state before design so the build didn't loop back for rework.
  • Turned a vague brief into a decision-ready spec in Confluence, surfacing the messy states (stipulations, missing documents, permissions) and framing options so stakeholders committed before engineering started.
  • Defined the full broker deal lifecycle, from application intake through review, stipulations, and funding, then drove the specs to production with AI-assisted tooling.
  • Cut a 750-page site refresh from an estimated 8 months to 2.5, building multi-agent Claude Code workflows, custom skills, and MCP servers that automated design-system application across WordPress.
  • Dropped bounce rate from 40% to 13% on the refreshed site.
