Engineered a multi-module application architecture, improving project build times and reducing feature implementation time.Led the development of a feature that allowed users to create custom datasets by selecting objects on photos with their fingers. This feature received positive feedback, eliminated the need for external image labeling tools, and sped up AI model data preparation, training, and deployment.Configured Hilt for Dependency Injection, which reduced module integration errors and improved component testability.Covered UI tests using Espresso, minimizing the occurrence of regressions and accelerating the overall testing process. This enhancement led to higher release quality and greater stability in production builds.Migrated networking and database operations to the common module using Kotlin Multiplatform Mobile, ensuring code reusability across Android and iOS platforms.Implemented CI/CD processes, decreasing deployment time and increasing release frequency. Achieved comprehensive code coverage through automated testing, reducing production bugs.Improved code standard adherence through Detekt integration, simplifying the code review process and enhancing overall development efficiency.Technologies: Kotlin, Kotlin Multiplatform Mobile, Coroutines, Jetpack Compose, Hilt, Espresso, CI/CD, Detekt, Multi-module architecture.

Created and launched an open-source course covering Android, iOS, and Kotlin Multiplatform within4 months, effectively reducing the intern training period from 5 to 2 months.As part of a team of two, successfully developed banking template app from concept to completion on iOS and Android using KMP, XML for Android, and XIB for iOS. Refactored finance operations Java SDK to Objective-C, meeting all project deadlines, and releasing stable applications.Participated in developing and fixing open-source KMP libraries MOKO and managed their deployment process. This relieved our CEO and allowed him to focus more on non-routine issues.I have given talks at conferences about Kotlin Multiplatfrom benefits and course written by me to became familiar with that technology. DUMP 2022, IT City 2022.Transitioned the detailed session view feature for Campus from Java and XML to Kotlin and Jetpack Compose, reducing the codebase and improving screen load times.Optimized UI components for the Campus app, enhancing responsiveness and overall UX, leading to a decrease in time required for future updates.Technologies: Kotlin Multiplatform (KMP), Jetpack Compose, XML, XIB, Objective-C, Java, MOKO, iOS, Android, SQLite.
