1. A non-transitory computer-readable medium embodying a program executable in at least one computing device, the program, when executed, causing the at least one computing device to at least: obtain, from a client device, a packaged executable application comprising at least one user interface layout optimized for a first display type, the at least one user interface layout being encoded in Extensible Markup Language (XML); determine, as a function of the at least one user interface layout, if the packaged executable application is unoptimized, based at least in part on a predefined condition, for a second display type distinct from the first display type; apply, responsive to the packaged executable application being unoptimized for the second display type, an XML pattern matching function to an XML encoding of the at least one user interface layout to match the at least one user interface layout with at least one XML pattern; select a plurality of optimized user interface templates as a function of the at least one XML pattern; obtain, from the client device, a selection of a one of the optimized user interface templates; encode for rendering by the client device a user interface to facilitate a modification of the selected one of the optimized user interface templates, the modification generating a modified optimized user interface template; apply at least one XML transformation to the at least one user interface layout as a function of at least one of the selected one of the optimized user interface templates or the modified optimized user interface template, generating an optimized user interface layout, the optimized user interface layout conforming to the selected one of the optimized user interface templates or the modified optimized user interface template; and generate an optimized executable application by repackaging the executable application to further comprise the optimized user interface layout.
