Building Applications with NYC Open Data and Open Source Tools

Christian Casazza is a data engineer who has built a open-source data platform on top of NYC Open Data. In this talk, he discusses using open source data engineering tools like Dagster, Polars, and DuckDB to ingest and clean gov data like NYC 311 and from the NYC Checkbook API. He will show participants how they can build on top of the clean, curated government data to build applications for the public good.

Anyone who is interested in using government data to improve the city’s operations and citizens quality of life should attend.

The first part of the event will involve understanding the core open source technologies anyone working with data should know. Understanding the logic behind open source tools is important to appreciate how much faster, cheaper, and simpler modern data app building is with open source tools. These tools can be applied for anyone’s civic interests and day to day work. The second part of the event will discuss some of the tools I’ve built around open source data. We will discuss using QueryStation.app and NYCStats.app and how New Yorkers can go there to learn about their city.
