Learn practical data governance strategies to eliminate data debt and transform chaotic data management into systematic engineering practices in this 30-minute conference talk from EuroPython 2025. Discover how accumulated technical shortcuts, missing data contracts, and deferred maintenance create compounding problems that manifest as broken dashboards, escalating costs, and constant crisis management. Explore real-world governance approaches including data contracts, semantic layers, and product-oriented data management that proactively prevent issues rather than reactively addressing them. Master techniques to stop data chaos at its source, understand why data contracts and semantic layers are essential tools for data engineers, and implement small governance adjustments that significantly reduce costs while improving data quality. Gain hands-on strategies for making data governance practical and accessible for engineering teams, enabling you to build robust data systems that scale effectively rather than constantly requiring emergency interventions.
