Lightning talk

"TestScribe, a "low code/no code" testing tool" presented by Ray Yang

TestScribe is a "low code/no code" tool to make Python testing easier by automating the boring and repetitive parts. It allows you to quickly start an interactive testing/debugging session without having to write boilerplate code. As a bonus, you can save the session as a complete unit test for further debugging or regression testing.

Main talk

"Hamilton: Natively bringing software engineering best practices to python data transformations" presented by Stefan Krawczyk

At Stitch Fix, a data science team's feature generation process was causing them iteration & operational frustrations in delivering time-series forecasts for the business. It wasn't the scale of data that was the problem, it was their code. In this talk I'll present Hamilton, a novel open source Python framework that solved their pain points by changing their working paradigm.

Specifically, Hamilton enables a simpler and more productive approach for data science & data engineering teams to create, maintain, execute, and scale both the code (human) and computational sides of feature/data transforms. In this talk I'll cover the motivation & backstory, what the Hamilton paradigm is and how it works, and how it naturally guides you into doing software best practices without really thinking about it.
