Projects
Air Alarm 06/2023 - Present

Developed a high-scale Android application with millions of active users, providing real-time regional air-raid and
hazard alerts. The app was built with MVVM architecture and Kotlin Coroutines, supporting both GMS (FCM) and HMS
(Huawei Push Kit) for broad device compatibility. I implemented a robust networking layer with Retrofit and OkHttp,
while persisting user subscriptions and alarm states via Jetpack DataStore. To ensure timely delivery of alerts, I used
a foreground service for continuous background operation, while exact alarms were applied for critical scheduled
events such as the daily “Moment of Silence.” Notifications were enhanced with custom audio playback using Media3
ExoPlayer, and the app integrated Google Maps SDK to let users set precise coordinates for more relevant “Increased
air threat” alerts. The application supports two languages, allowing users to select their preferred interface. Additional
improvements included in-app updates via Play Core and monitoring with Firebase Analytics and Crashlytics.

Alarm map. Widget 04/2024 - Present

Developed an Android application that visualizes real-time emergencies across Ukraine on an interactive map,
providing users with up-to-date regional alerts. The app was built with Kotlin, MVVM, and Clean Architecture,
featuring a reliable networking layer using Retrofit and OkHttp, with event streaming handled via Centrifugo
WebSocket. To improve accessibility, I implemented a home screen widget (AppWidgetProvider) that allows users to
track critical alerts without opening the app, ensuring immediate access to important data. The app also included
monetization features such as banner ads integrated with Google AdMob, along with a subscription option to disable
ads and unlock an ad-free experience. The solution leveraged Jetpack ViewBinding, Navigation Components, and Koin
for dependency injection, while Firebase services supported analytics, stability, and targeted updates.

Anycar 05/2025 - Present

Developed an Android application that enables users to quickly rent vehicles or generate income by renting out their
own cars. The app was built with Kotlin using MVVM and Clean Architecture, featuring a modern UI implemented with
Jetpack Compose and Navigation Compose. Implemented OTP-based authentication for secure user onboarding and
designed the system to support two distinct roles—car owner and renter—allowing users to seamlessly switch
between them. Real-time updates, including booking confirmations and in-app chat, were powered by Centrifugo
WebSocket, ensuring instant synchronization across devices. Networking was handled with Retrofit and OkHttp, while
Coroutines enabled efficient asynchronous operations. Images and video media were managed using Coil, Coil
Compose, Tus Android client, image-compressor, video-composer, and image-zoom libraries. Dependency injection
was implemented with Hilt, and Firebase was used for push notifications, analytics, and crash reporting.

Ukrenergo 04/2024 - Present

Developed an Android application that provides users with real-time information on regional energy supply status and
predictive changes in the power system. The app was built with Kotlin using MVVM and Clean Architecture, with
dependency injection implemented via Koin. Networking and REST API integration were handled using Retrofit with
Gson, while OkHttp and logging interceptors ensured reliable network communication. Implemented ViewBinding for
efficient UI management and SwipeRefreshLayout for intuitive data refresh. The app supports two languages and two
themes, allowing users to configure their preferences on the settings page. To improve usability, frequently accessed
data is cached for offline availability. Push notifications are handled via Firebase Messaging, and Firebase Analytics
and Crashlytics are used for monitoring and stability. Asynchronous operations and background tasks are managed
with Kotlin Coroutines, ensuring smooth, responsive user interactions.

Anyclip Android Player SDK 04/2024 - Present

Developed an Android SDK and accompanying demo application for video playback, enabling seamless integration of
a fully customizable video player into third-party apps. The SDK was built with Kotlin and focused on flexible, modular
design for easy integration. Media playback was implemented via Media3 ExoPlayer with support for HLS streaming
and IMA ads, while the UI leveraged Media3 UI components for player customization. Networking was handled with
Retrofit and OkHttp, with Moshi for JSON serialization. Kotlin Coroutines ensured smooth asynchronous operations
and responsive playback. Dependency injection was implemented with Koin, and image loading was optimized with
Glide. The demo app showcased the SDK’s capabilities and included navigation using AndroidX Navigation
Components.

Whizzy 02/2023 - Present

Developed a comprehensive Android logistics system consisting of two separate applications for clients and drivers,
enabling users to create, track, and fulfill orders efficiently. Real-time updates, including order status changes, are
powered by Scarlet WebSocket, ensuring instant synchronization across both apps. Networking was handled with
Retrofit and OkHttp, with Gson for JSON serialization, while asynchronous operations were managed using Kotlin
Coroutines. Data persistence and offline support were implemented with Room. Dependency injection was handled
with Dagger, and Android Architecture Components (ViewModel, Lifecycle) were used for state management. The UI
leveraged ViewBinding, Material Components. Google Maps SDK, Places SDK, and Maps Utils were used for drivers
navigation. Images were managed using Glide, Glide Transformations, EasyImage, and Compressor, and runtime
permissions were handled using Dexter. Firebase services were integrated for push notifications, analytics, and crash
reporting, and RxJava2/RxKotlin was used in the client app for reactive programming where needed.

TaskRunner & TaskRunner for Runners 02/2023 - Present

Developed a high-scale Android platform connecting two user roles—executants (task performers) and posters (task
creators)—allowing posters to create tasks, select executants, and manage task fulfillment with payment processing.
The runner and poster apps feature real-time updates for task status and notifications via Firebase Cloud Messaging.
Networking was implemented using Retrofit and OkHttp, with Gson for JSON serialization, and asynchronous
operations were managed using RxJava2/RxKotlin. Room was used for local data persistence, and Dagger provided
dependency injection. Architecture components such as ViewModel and LiveData were employed for state
management, while the UI leveraged ViewBinding, Material Components, Google Maps SDK, Places SDK. Images
were handled with Glide and EasyImage, while user input was supported with Dexter, Input Masks, and RxLocation.
Additional integrations include Segment Analytics and Facebook SDK for analytics, marketing, and social features.
