Employment

  • Co-founder | CTO

    2017 - PRESENT
    Stepwise Analytics
    • Oversaw the development of Stepwise's applications and guided the company's overall technology strategy.
    • Created a system to generate detailed, data visualization-rich automated reports for every property across the cities the company supports.
    • Built a vector tile server to dynamically render tiles based on queries across hundreds of thousands of properties.
    • Constructed data exploration tools to help company developers understand the historical accuracy of their machine learning models at any point.

  • Founder | Urban Technologist

    2015 - PRESENT
    Poe Public
    • Implemented participatory budgeting maps for the city council of NYC. Thousands of ideas are submitted across 20+ participating council districts each year. Also worked on participatory budgeting projects with Long Beach, CA, Greensboro, NC, and Cambridge, MA.
    • Developed idea collection maps for Miami Foundation's public space challenge. This included a rating/judging component through which they determined how to allocate $300,000+ each year.
    • Worked with the NYC city council to vet and provide suggestions for improvements on their legislative management system (Legistar) API.
    • Created a map-based survey to prepare the bicycle transit systems and the city of Los Angeles's bike-share rollout.
    Technologies: Django, MapBox, LeafletJS, Backbone.js, Marionette.js
  • Digital Services Architect

    2015 - 2017
    City of Philadelphia, Open Data & Digital Transformation (ODDT)
    • Researched, designed, and developed processes and tools to help city departments collect, use, and release data.
    • Developed an interim homeless management information system for the Office of Supportive Housing to help them avoid regressing to a paper-based data collection system which would have jeopardized their ability to deliver HUD reports required for a significant portion of their funding.
    • Implemented an interactive data visualization of occurrences of “bullet voting”—when voters choose only one of five allowed candidates for at-large council positions—during the 2015 city council primary election. The visualization allowed the city controller’s office to communicate a confusing phenomenon to the general public.
    • Researched and began designing processes to centralize deployment, management, and reporting around the City’s ETL pipelines. Based on the challenges that ODDT faced around ETL, identified, and began implementing an instance of Airflow. Also began documenting recommendations on how ODDT should be building ETL scripts, using petl as a data transformation and validation library.
    Technologies: Django, Airflow, LeafletJS, C3.js
  • Software Developer

    2012 - 2015
    OpenPlans
    • Worked on a small team with amazing people on projects that empower people to get involved in planning for the future of their communities and cities.
    • Helped to develop Shareabouts, a flexible tool for gathering geography-specific public input. Primarily responsible for developing the Django REST framework-based Shareabouts data server, reporting tools, and core parts of the mapping interface.
    • Built a product called OpenPlans, an outgrowth of our experience building tools and websites for urban planning projects. Worked on many parts of this project: server-side data management, external service integration, APIs, browser-side interface development, and testing.
    Technologies: Django, Flask, LeafletJS, Backbone.js, Marionette.js

Experience

  • Shareabouts (Development)
    https://github.com/openplans/shareabouts

    Shareabouts is an online mapping tool to gather crowdsourced public input in a social and engaging process. Using Shareabouts, people can drop a pin on a map to provide ideas, suggestions, and comments for planning and design issues. Also as a mobile-friendly application, Shareabouts makes it easy to add input on the go.

    Shareabouts is used by governments and public interest organizations throughout the United States. I was the original author and continue to be a primary maintainer of the platform.

  • Django REST Framework CSV (Development)
    https://github.com/mjumbewu/django-rest-framework-csv

    Django REST Framework CSV is a plugin that generates CSV-formatted output for REST endpoints.

    I originally developed this plugin for the Shareabouts project, and I continue to maintain it. It has become a popular project, as API CSV-generation is a need more common than I initially anticipated.

  • Councilmatic (Development)
    https://www.councilmatic.org/

    In 2011, I began an open source project called Councilmatic in Philadelphia. The purpose was to make access to primary materials—bills, resolutions, and more—being produced by local legislative bodies easier to access and understand. The project has since spread to Chicago, LA, and NYC with several other cities interested in setting up instances.

  • Cyborg City (Other amazing things)
    https://github.com/mjumbewu/cyborg-city-presentation

    I developed a method of analysis called a conversational exploration of hypothetical futures which I used to prepare for a series of presentations called The City as Cyborg: A History of Civic Technology in The First Quarter of The 21st Century.

    In these presentations, I embodied a historian from the year 2056 looking back at the developments in the relationship between humans and digital technology over the first quarter of the 21st century. The first presentation was given at DjangoCon 2016, and I spoke about the process at Ignite Philly 19.
