We have built custom web applications in .Net since version 1.1 and are currently building applications in version 4.5 with C# as the primary language.
In addition to building out websites from scratch there are many off the shelf software platforms written in PHP that can be easily customized.
Customers are able to log in, submit secure invoices or payments and, at the same time, are able to track payments and invoices.
Responsive web applications are built to allow websites to be viewed on the many different sizes of screens available to the typical user today.
Our small teams are mainly dedicated to Ruby on Rails and .Net applications.
Ruby is a fantastic language to build business applications with complex workflow, large data, and robust reporting needs.
