About

I’m a senior engineer at TimeShareWare, where I rebuilt the Room Matrix, a drag-and-drop board resort operators like Vidanta use to manage their rooms. It’s the kind of UI I love: dense, fast, and hard to get right.

Before that I led a team of seven at Readeo to ship a family reading app, and I was one of the first five employees at LowestMed, which grew 7x and was acquired by RetailMeNot.

These days I work in React and .NET, lean on Claude Code every day, and am happy to pair on a problem in English or Spanish.

Building the tools resorts run on

TimeShareWare makes the platform that 15 large resort operators across multiple countries, including Vidanta, use to run their timeshare business. I work across the React/Redux frontend and the C# / .NET backend, and I’m the team’s go-to for design and styling.

The Room Matrix

Sample data

A tiny version of the board I rebuilt. Drag a stay or a maintenance block to another room or night. Overlaps are rejected, just like the real thing.

  • Rebuilt the Room Matrix with drag-and-drop. Staff assign reservations to rooms, move dates, and block rooms for maintenance right on the board.
  • Replaced a board that couldn’t drag at all and had recurring problems assigning rooms and displaying stays correctly.
  • Used by resort teams in multiple countries across our 15 enterprise clients.

Reservation booking

Helped build out the booking flow guests and staff use to reserve stays.

Design & styling lead

The go-to for design updates. Redesigned many layers of the application.

AI-assisted dev

Claude Code has sped up how fast I ship and learn, and helps our team get a lot more done.
