About Us

In 2009, DEVSENSE was founded by four software engineers with years of practical and theoretical experience about software research and development. Their first -and still ongoing project- comes from their university research. Phalanger - the open-source PHP language compiler for .NET Framework, required high understanding of PHP and .NET internals. This work involved a deep cooperation with the Microsoft Research members and the Microsoft development team in Redmond.

The company is based in Prague, Czech Republic. It became a Microsoft Partner, providing tools and support for improving PHP web sites efficiency and security on Microsoft platforms. While working on a PHP compiler, DEVSENSE team members gained knowledge of PHP internals. This helped to create the PHP analysis methods used in the compiler and in the smart code editor for PHP Tools for Visual Studio.

To provide the best user experience and to move forward the cooperation with the Microsoft development team, DEVSENSE became a Visual Studio Industry Partner. Since the public availability of PHP Tools for Visual Studio, the company is providing development tools for thousands of customers. The development team is working hard to create a powerful, smart, easy-to-use and productivity-enhancing Visual Studio integration, targeting software development professionals who rely on a fast and intuitive environment.
