When not building data systems, Dan enjoys painting and playing the banjo.
“I’ve known Dan for at least 8 years and have always found him to be responsive, attentive to details, and honest. Our work as a military and government contractor has at times required customized solutions. Dan built a custom dark-web search engine which we used for government and corporate clientele. This proved to be one of our biggest successes and produced results that had a very significant impact on national security, while also helping us serve our favorite financial-services clients. Dan operates with the necessary level of integrity required for such efforts and I hope we can partner with him for a long time to come.” – Morgan C.
