Devsense is a company focused on software solutions, specifically for PHP development, with over 10 years of experience. It provides tools and support for improving PHP website efficiency and security on Microsoft platforms to thousands of customers around the world. It 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 a high understanding of PHP and .NET internals. This work involved deep cooperation with Microsoft Research members and the Microsoft development team in Redmond. Devsense is based in Prague, Czech Republic.
