  1. Object-oriented PHP 5+ programming. OOP concept provides a clear modular structure for programs, makes it easy to maintain and modify existing code, and provides a good framework for code libraries. All combined, it makes your PHP solution easy to support and reduces development and maintenance costs.

  2. Using popular CMS: WordPress, Drupal, Joomla, and more. Whenever possible we use trusted out-of-the-box CMS solutions and customize them to your needs. We install all necessary plugins and appropriate extensions to give full flexibility in the way your content is presented.

  3. Attention to best practices like design patterns and unit testing. We use design pattern that help us employ best practices in building an application or system. Unit tests ensure that code meets its design and behaves as intended, and enable us to find problems early, facilitate change and simplify integration.

  4. Orientation on the highly modular Model-View-Controller design. Using MVC design pattern we deliver highly custom web applications that can display multiple views of the same data at the same time and make it easy to accommodate changes in user interfaces.

  5. Implementation of reusable and easier to maintain source code. This principle enables code-level knowledge transfer, increases application maintainability and reduces your total cost of ownership.
