I help small | medium technical teams deliver the damn software

The goal is quality software, a wicked sharp team and good sustainable business.

I achieve results with technical skills and by fostering a sustainably productive culture suited to software development.

I bring experience and a powerful professional network. You have the business, I know the technology and the people who make it tick.

LiveView on Nerves

I haven't run into any short compelling demos of getting these started together.
