Two Years with Kotlin Multiplatform: A Fintech's Journey to Innovation
Two years ago, StoneCo, one of the largest fintech companies in Latin America, embarked on a journey to unify its mobile applications using Kotlin Multiplatform (KMP), aiming to balance code-sharing efficiency with the seamless user experience required in the fintech sector. This talk explores our journey—how we evaluated multiple cross-platform frameworks, overcame both technical and organizational challenges, and achieved 40% shared code across two large-scale mobile apps serving over 4 million users.
You'll hear how we made the decision to adopt KMP, how we trained 130 mobile engineers to embrace this paradigm shift, and the measurable impact it had on team productivity, developer satisfaction, and app performance. Whether you're considering KMP or scaling it within your organization, this session will provide actionable insights from a real-world, long-term implementation.
