I specialize in Flutter, Kotlin, Kotlin Multiplatform, Jetpack Compose, and modern Android architecture patterns such as MVI and MVVM. I have a strong track record of improving app quality and delivery speed, including reducing build times, lowering crash rates, and increasing test coverage through better CI/CD and automated testing. I enjoy working on modular, maintainable systems and applying Clean Architecture and TDD principles to deliver reliable mobile products. I have also led and mentored remote international teams, helping junior engineers grow through code reviews, best practices, and collaborative Agile development. My background includes both Flutter and native Android development, with experience in performance optimization, offline-first architecture, and integrating complex third-party services and SDKs. ## Skills ### [Python](https://jobicy.com/talent/python.md)[SQL](https://jobicy.com/talent/sql.md)[Java](https://jobicy.com/talent/java.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Git](https://jobicy.com/talent/git.md)[Jenkins](https://jobicy.com/talent/jenkins.md)[GraphQL](https://jobicy.com/talent/graphql.md)[RESTful APIs](https://jobicy.com/talent/restful-apis.md)[Kotlin](https://jobicy.com/talent/kotlin.md)[Unit Testing](https://jobicy.com/talent/unit-testing.md)[GitHub Actions](https://jobicy.com/talent/github-actions.md)[XML](https://jobicy.com/talent/xml.md)[Android](https://jobicy.com/talent/android.md)[Junit](https://jobicy.com/talent/junit.md)[Gradle](https://jobicy.com/talent/gradle.md)[Flutter](https://jobicy.com/talent/flutter.md)[Firebase](https://jobicy.com/talent/firebase.md)[Navigation](https://jobicy.com/talent/navigation.md)[Flow](https://jobicy.com/talent/flow.md)[Stripe](https://jobicy.com/talent/stripe.md)[MVVM](https://jobicy.com/talent/mvvm.md)[Dart](https://jobicy.com/talent/dart.md)[UI Testing](https://jobicy.com/talent/ui-testing.md)[Jetpack Compose](https://jobicy.com/talent/jetpack-compose.md)[Retrofit](https://jobicy.com/talent/retrofit.md)[Espresso](https://jobicy.com/talent/espresso.md)[Android SDK](https://jobicy.com/talent/android-sdk.md)[Mockito](https://jobicy.com/talent/mockito.md)[Coroutines](https://jobicy.com/talent/coroutines.md)[Fastlane](https://jobicy.com/talent/fastlane.md)[Google Maps](https://jobicy.com/talent/google-maps.md)[Kotlin Multiplatform](https://jobicy.com/talent/kotlin-multiplatform.md)[ROOM](https://jobicy.com/talent/room.md)[OkHttp](https://jobicy.com/talent/okhttp.md)[MVI](https://jobicy.com/talent/mvi.md)[ProGuard](https://jobicy.com/talent/proguard.md)[Robolectric](https://jobicy.com/talent/robolectric.md)[MockK](https://jobicy.com/talent/mockk.md)[LiveData](https://jobicy.com/talent/livedata.md)[Data Binding](https://jobicy.com/talent/data-binding.md) ## Tech Stack & Tools ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/firebase/firebase-original.svg) Firebase](https://jobicy.com/talent?tool=firebase.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jenkins/jenkins-original.svg) Jenkins](https://jobicy.com/talent?tool=jenkins.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/gradle/gradle-original.svg) Gradle](https://jobicy.com/talent?tool=gradle.md) ## Experience Senior Flutter Developer @ Devotel Apr 2024 - Present Led development of a cross-platform fitness and habit-tracking application built with Flutter, Dart, and MVVM/MVI patterns, serving 400K+ monthly active users and achieving a 4.7 Play Store rating.
