I would invite the author to have a look at the open-source code repository GitHub. Everyone is free to post their code on this site for the world to see, download, collaborate on etc. While some people post there as part of their job, most do so on their own time and dime; at least with the latter, there is no HR department to promote women, nor is there any unspecified old boys' club to get in their way.  

There are roughly 20 times more men than women on GitHub.
