PyData Warsaw #25

All the ML/AI in 2025!

We would like to invite you for the next PyData Warsaw Meetup - 2 great speakers, tons of knowledge and discussions

19:00 - Piotr Mierzejewski, Sunscrapers - "Overview of Data Test Types in dbt: From Built-In to Custom Solutions"

About Topic: Ensuring data quality and the correctness of analytical logic is a crucial part of data pipelines. DBT offers a powerful framework for testing, but it also comes with certain limitations. In this session, we will explore the various types of data tests available in DBT and discuss custom approaches you can implement to address specific challenges and tailor testing to your unique needs.

About Speaker: I am a Data Engineer with over 4 years of experience and a solid academic background in computer science. Throughout my career, I have worked on projects in the petrochemical, recruitment, healthcare, and financial sectors, which has given me a broad understanding of data across different contexts. This experience allows me to quickly grasp the business goals behind the data and to manage and transform it in ways that generate the greatest value for the organization. On a daily basis, I work with Python and SQL technologies, which are my primary tools. I value these languages for their versatility and capabilities, but I am equally comfortable supporting projects that use Java, JavaScript, or C#. I am not limited to a single technology stack and can quickly adapt to new tools to complete tasks effectively. I have also supported projects from the front-end side (React) and taken on roles as a tester or team leader when project needs required it. I am confident that my flexibility and readiness to take on different roles within a team contribute to achieving the best results. I approach my work with a craftsman’s mindset, focusing on building practical, reliable solutions that solve real problems. I'm committed to constantly improving my skills, adapting to new tools, and finding efficient ways to make data truly useful. For me, success means delivering solid results and adding genuine value to each project I take on.
