Mariatta Wijaya is a multi-award-winning open source maintainer and contributor with over 20 years of software engineering experience. A Python core developer focused on workflow and documentation, she advises and administers Global PyLadies, co-founded PyCascades, and formerly chaired PyCon US, PyCascades, and PyLadiesCon.

Dan and Mariatta discuss why unreviewed AI-generated contributions burden CPython maintainers, even as Mariatta uses AI to write code. She shares how she reviews plans and results, records decisions, and builds Claude skills to prevent agents from repeating mistakes.

They also discuss her self-hosted personal apps, the limits she places on AI advice, and how she uses AI to help promote community events while keeping time for speaker mentorship. Mariatta explains why agent instructions should be useful to humans and why she packages recurring work as reusable scripts.
