pyOpenSci Executive Director Leah Wasser returns to UN Open Source Week as a sponsored maintainer, supported by the Sovereign Tech Agency. This year she will facilitate a session on open source and AI tools — and participate across a full week of programming spanning maintainer sustainability, AI, digital public infrastructure, and open source policy.
