PROFESSIONAL EXPERIENCE
Android Software Engineer | Grid Dynamics
Dec 2021 – Present
International cross-functional Agile teams building production Android apps for e-commerce and smart home clients.
Fashion E-commerce Platform — Customer-facing Android App
• Cut production crash volume by driving root-cause investigations through Firebase Crashlytics and Quantum Metric session
replay, then shipping targeted fixes and non-fatal diagnostic logging for hard-to-reproduce issues.
• Modernized the legacy codebase by migrating XML UI to Jetpack Compose, RxJava to Coroutines/Flow, and
LiveData/SingleLiveEvent to StateFlow + MVI, improving maintainability and reducing boilerplate.
• Shipped customer-facing features end to end, owning requirements clarification, estimation, implementation, testing and code
review — consistently delivering on sprint commitments in a multi-module Gradle/CI-CD codebase.
• Raised test coverage and code quality by writing unit tests (JUnit, MockK) for ViewModels, use cases, repositories and
network/data layers, and by leading code reviews focused on Kotlin/Android best practices and maintainability.
• Hardened the networking layer with Retrofit/OkHttp interceptors, structured error handling, retry logic, and DTO-to-domain
mapping, reducing network-related edge-case bugs.
• Reduced post-release risk by owning Crashlytics monitoring after each release, triaging issues by severity/impact, and
unblocking teammates on Android/Kotlin questions and failed CI builds.
Smart Home Platform — Multi-Room Device Management App
• Designed and shipped a synchronized dual-list UI (room selector + device list) that stayed in sync during scroll, improving
usability for managing devices across multiple rooms.
• Built adaptive layouts for single-pane portrait and dual-pane landscape, extending tablet/large-screen support without a separate
codebase.
• Improved app stability and maintainability by resolving production issues and refactoring high-churn areas of the codebase,
backed by a growing unit test suite (JUnit).
