Firm Solutions was great to work with. We had a pretty complicated custom API we need to build and they were able to understand what we needed within our first meeting. Since we are local, they even paid a visit during the build to make sure we were all on the same page. During the middle of the build for our larger project, we started and completed a second smaller project as well. Very satisfied.
