Enrico Fantini

Hello there! I’m a Senior Android Engineer based in Cesena, in North-Eastern Italy. Since earning my M.Sc. from Università di Bologna I’ve spent 8+ years designing and shipping production Android apps end-to-end, from requirements to Play Store, across fintech (crypto wallets), consultancy and IoT, often leading and mentoring small mobile squads. These days I work mostly in Kotlin and Kotlin Multiplatform, and I’m an early, daily adopter of AI-augmented development with multi-agent coding harnesses.
