I am the co-owner of a small software development firm based in Washington, DC. We have a web-based hybrid CRM/Applicant tracking product called PeopleMatrix. In addition to the off-the-shelf build we use the PeopleMatrix engine (and other technologies) to build custom-tailored CRM, financial and business process automation systems. A lot of this custom work involves integration with heterogenous and legacy environments. It's great to design and build a system that people use to solve real problems and I love the intellectual challenge.
