We design, build and maintain software for the web, the desktop, the iPhone and the browser itself. Senior engineering, measured by what ships.

ESUIT DEV is an independent software studio run by a senior engineer. The person you talk to is the person writing your code.
Years of designing, building and operating software in production mean caring as much about a product's second year as its first release.
