Tim is a full-stack generalist and passionate teacher who loves working with people as much as he loves to code. He believes the best developer is one who is well-informed of specifics and can also make deep connections between software development and the broader world. He has recently been exploring non-relational data stores, why professionalized product management is a global suboptimization, and of course everything related to Git. He does not really believe that it is possible to teach, but rather believes that it is his responsibility to create an environment in which people can learn.

He is also a poet, having composed and produced companion videos for Oh, The Methods You'll Compose and The Maven, with another project currently in the works. If you've been in his Git classes, you've seen some famous poems make their way into the world's best version control system.

I started my career as a programmer, and over the years I’ve worn many hats, including business owner, internal consultant and manager. From all these perspectives, one thing became clear: our level of individual, team and company success was deeply impacted by our work environment and organizational dynamics. As a result, I have spent the last twenty-five years helping companies design their environment, culture, and human dynamics for optimum success.

I’ve written over 100 articles, and co-authored two books–Agile Retrospectives: Making Good Teams Great and Behind Closed Doors: Secrets of Great Management. I write about management, leadership, collaboration, organizations and change (or another topic I’m currently exploring).
