Retired - NOT!... I still spend my days writing code! Most recent contribution is the the GitHub ndexbio/openapi-specification repository. The application runs at http://openapi.ndextools.org.
My zen is to integrate new heterogeneous software technologies into tools that absolutely "WOW!" software developers, scientists and academicians. This involves scouting out new open-source projects, and making them "play nice" with other open-source code bases. While I was once paid to do fun stuff like this, today I do it for free.
