Jarek Potiuk

Independent Open-Source Contributor and Advisor, Committer and PMC member of Apache Airflow, Member of the Apache Software Foundation, Security Committee Member of the Apache Software Foundation. Organizer of community-focused events, speaker.

Jarek is an Engineer with a broad experience in many subjects - Open-Source, Cloud, Mobile, Robotics, AI, Backend, Developer Experience, Security, but he also had a lot of non-engineering experience - building a Software House from scratch, being CTO, organizing big, international community events, technical sales support, pr and marketing advisory but also looking at legal aspects of security, licensing, branding and building open-source communities are all under his belt.

With the experience in very small and very big companies and everything in-between, Jarek found his place in the Open Source world, where his internal individual-contributor drive can be used to the uttermost of the potential.

Modern Python monorepo for Apache Airflow
Jarek Potiuk

Explore how Apache Airflow modernized its massive monorepo by transitioning from complex custom scripts to official Python packaging standards and tools like uv. This session breaks down the management of 120+ distributions, the implementation of modular pre-commit hooks, and a novel approach to "static" shared libraries within a single repository. Join us to see a real-world blueprint for large-scale modularity as we advocate for the formalization of a Python workspace standard.

Death by a Thousand Prompts: Can Our Disclosure Standards Survive AI Slop?
Jarek Potiuk

AI-generated "slop" is overwhelming vulnerability triage and burning out maintainers. This session focuses on building a unified framework to identify and "black-hole" synthetic noise at scale. We will discuss practical, cross-platform strategies to automate the rejection of low-signal reports and protect engineers from the unsustainable volume of AI-augmented disclosures.
