Senior🎓
Top SchoolHumberto Costa is an Android Developer with 8 years of hands-on experience building high-performance, user-focused mobile apps from São Paulo. He excels in Kotlin and Java, modern architectures (MVVM/MVI/Clean), Jetpack Compose, and offline-first solutions, and has led large refactors including a Java-to-Kotlin migration to modernize codebases. Humberto pairs deep platform knowledge (Hilt, Koin, Room/Realm, WorkManager, Retrofit/Ktor) with practical CI/CD expertise (GitHub Actions, Fastlane, Buildkite) to improve reliability and release cadence. He has driven product improvements in health tech—integrating Health Connect and privacy-aware data flows—and contributed to cross-platform interoperability with Flutter on Android. Known for balancing intuitive UI craftsmanship with measurable performance optimizations, he’s continually learning low-level and legacy stacks too, as hinted by earlier work across C#, Ruby and even Assembly.
