From 2011 to 2015, I worked alongside a partner of mine, Bret, on a product called Winsitter. We worked in a distributed environment. Most days were within our own homes, while other days might have been a coffee shop or diner.
Our development environments were distributed as well. I am primarily a Windows developer. My livelihood has been building ASP.NET applications. Visual Studio and Windows are my tools!
Bret, on the other hand, was all Macbook and OSX.
