Top SchoolSergey Lapin is a Senior Android Engineer based in Berlin with 9 years of experience building consumer finance and gig-economy apps and shipping features end-to-end. He combines deep Android UI and architecture expertise—Jetpack Compose, MVVM, Coroutines—with hands-on experience modernizing legacy Java codebases and designing backend APIs. Sergey also specializes in the Gradle build system and CI/CD, driving modularization, build performance improvements, and GitLab pipeline optimizations to speed development at scale. At Vivid Money he led subscription UX reinvention, helped build a credit product from scratch, and contributed design-system components that bridge product and engineering.
