Charles has worked on several complex software projects for Modular Robotics.  I call him first when I have a development project that is nebulous; he has a great ability to parse a problem into solvable projects and then complete those projects using a wide variety of languages and frameworks.  I've worked with many talented developers, but Charles has the rare ability to think about software projects at not just the nitty gritty code level, but at the abstract, integrative level as well.

Charles has done the programming on a web-based project that we began in February 2009. I am very pleased with the results on this first version. Charles has shown a great deal of technical knowledge as well as a good grasp of development and user issues that needed to be considered for the project. In addition, I feel he has demonstrated the highest levels of integrity. I intend to continue working with him on upgrades and enhancements to the product. I would strongly recommend him.
