Legion of Tech Volunteers Lead a Charge for Bernie Sanders

Dawn crept into Daniela Perdomo’s Brooklyn apartment, her bleary eyes still focused on her bright computer screen. The founder of a nearly three-year-old communications start-up, she had been up all night again, orchestrating the work of more than 100 other developers, web designers, researchers and writers. But they were not working for Ms. Perdomo’s company. They were not even getting paid. Instead, the all-night sessions were devoted to the Aug. 12 unveiling of FeeltheBern.org -- a website they created to explain Bernie Sanders’s positions on issues in the 2016 presidential campaign.

Throughout the summer, a largely unseen legion of technology professionals across the country -- software developers and designers, product managers and more -- have been moonlighting online on Sanders’s behalf. They have been applying their initiative, creativity, organizational skills and, above all, technical prowess in their off hours to support an underdog candidate who has been more than grateful for the help.
