    Work full-time for a major UK Financial Institution. Spent many years developing and PMing technical teams. Totally converted to the TDD approach after reading the works of Uncle Bob and using it on some private projects (including an arbitrary precision integer math library written in C). Interested in small-scale stuff with reliable customers - not too much time commitment, but happy to be flexible, and if that works for all parties involved, maybe bigger projects in the future, once the trust relationships are in place.  less
