Adding custom packages to Open Network Linux

I want to use Open Network Linux for our whitebox switch solution and want to add my own applications to be built and installed with the OS.

Initial thoughts: I will probably build my custom applications into a deb package which can be pulled from a store such as artifactory to be build into the image.

What is the suggested method for where and how I should add these applications in? I just need advice on a work flow, for example if there is a concept of "recipes", as in a Yocto linux build, of where it would be a good idea to add my own applications.
