A system builds an application. The system receives, by a build server, from an application development server, metadata information of the application and a build request to build the application. The system generates binaries of the application by overlaying the metadata information on binaries of a pre-compiled application. The system then signs the binaries of the application to generate signed binaries of the application, and sends, to the application development server, a corresponding signature and one or more files modified by the signing of the binaries of the application. In one embodiment, the build server stores, on a storage appliance, the corresponding signature, the one or more files modified by the signing of the binaries of the application, and the metadata information of the application.
