Karavela: Scaling DevEx and compliance for 1,600 engineers at Stone

This talk explores the journey of Karavela, an internal platform that transformed Stone's engineering culture. The session focuses on the "platform as a product" mindset, demonstrating how to balance rigid financial compliance with an elite developer experience. The speakers discuss how they moved from friction-heavy manual audits to a "compliance by design" model, resulting in massive adoption and a near-perfect Customer Effort Score.

Key takeaways include:
• Compliance by design: How they baked PCI and SOX requirements into software templates to remove manual toil.
• The DevEx North Star: Using the Customer Effort Score to iterate on the platform and reach a near-perfect 6.9/7 rating.
• Proving ROI: How 30,000+ monthly deploys and 30% cost efficiency turned the platform into a strategic business asset.
