Who we are thankful for

These are the people that help us along the way.

Data Coordinators

Our data coordinators are responsible for coordinating the implementation of the open data work in their departments. Without their department knowledge and help, SF OpenData would not be possible.

Department of Technology

The Department of Technology supports us in developing and maintaining data pipelines for open data sharing and as partners on data architecture and infrastructure. A special acknowledgement to SFGIS within the department. SFGIS staff have been long-standing partners and champions for open data, providing support and expertise on automating data pipelines among other things.

Controller’s Citywide Services Auditor (CSA)

We’ve partnered with the performance team in CSA on a variety of projects, including the Data Academy, Stat program research, and internal data sharing.

Awesome Interns

We’ve had the opportunity to work with some amazing people on a short term basis. Their efforts have been key to moving some of our projects forward.

  • Charlie Moffett, Summer 2017. Charlie did the foundation research for what became the Ethics and Algorithm toolkit.
  • Sam Dorward, Fall 2015-Spring 2016. Sam joined us as part of an externship through Bain Consulting and knocked it out of the park conducting analytics work on tax compliance, fire inspections and evictions and created Advanced Excel for Data Academy.
  • Christina Malamut, Summer 2015. Christina joined us to help us research what it would take to improve public records requests in San Francisco, individual access to private data, and data about homelessness.
  • Laura Gerhardt, Spring 2015. Laura joined us as part of completing her Master’s in Public Policy at UC Berkeley. She researched and assessed how to best realize the value in housing inspections data across three City departments.
  • Charlotte Hill, Dan Wilcox, Evgenia Likhovtseva, and Marcelo Milanello, Spring 2015. As part of a client class project, this graduate team at UC Berkeley investigated options for data or technology partnerships with external groups.
  • Erica Finkle, Summer 2014. Erica joined us in Summer 2014 and provided the core research and basis for our project on streamlined internal data sharing. In a few short weeks, she reviewed and summarized the privacy laws facing SF, reviewed best practices in other jurisdictions, and provided a set of recommendations. Her work was put to immediate use and accelerated our learning curve.
  • Peri Weisberg, Summer 2014. Peri joined us in Summer 2014 and hit the ground running by informing the data categories on SF OpenData, helping us identify the best data licensing approach, and surveying metadata practices. Her core project was creating an evaluation framework for our open data program - something that had not been created to date. Most of her work is available on our resources page.
