I care about what happens after the code ships.
Does the interface make sense? Can the team build on it? Will it hold up when more people start using it? Those are the questions I bring to every project.
Over the past decade, I’ve built websites, mobile apps, and the systems behind them. Today, I partner with founders and teams to take products from an early idea through development and launch.

- Design, development, and deployment, considered together.
