Developer · Tool builder
I build practical web tools that get the job done.
I'm Robert Bettencourt. This is a living showcase of the tools and projects I build — each one lives on its own subdomain and is designed to be fast, focused, and useful.

About
A bit about me
I'm a developer focused on building small, sharp web applications that solve real problems — from financial calculators to document builders to time tracking that fits real accounting workflows.
Everything here is built with care: responsive, accessible, and fast. Each tool runs on its own subdomain of r2d2dev.com, and this site is where they all come together.
