Jeff started his technology career working at tech savvy firms in the Philadelphia area such as Vanguard and Johnson & Johnson. At the time, he also was volunteering with Code for Philly and the Philadelphia Association of Community Development Corporations (PACDC) on an open data project to combine city information with crowd sourced knowledge to locate vacant properties in Philadelphia. Through this combination of experiences, he realized the contrast between how the private sector and government use software to manage their own operations and data, but also how they provide services to their customers/constituents.
