Custom Open Source Web Applications

A custom-built web application has the power to transform your business.

A well-planned, built, tested and deployed web application can help to automate and semi-automate your business processes. It can turn time-consuming manual tasks in lightning fast automated processes. It can represent an infinitely scalable workforce that never gets tired, never takes a break or a sick day, and never makes a mistake.

Whether your business is completely driven by web applications, or could benefit by automating or streamlining certain processes, Cornerstone can help. We have built a wide variety of custom open source applications for customers across different industries and geographies.
