The role holder:

The Application Architect is responsible for the overall design of an application, or several applications, ensuring that the application meets its functional and non-functional requirements. The individual would typically be an experienced software Engineer, expert in one or more development languages and is therefore able to set the direction of the design, development and methods used for a development team.
