I was hired to build new features and fix bugs before the final release of the app to the Google Play store. I worked remotely with other Android developers. The application helps the user to achieve financial goals.

Technologies: Kotlin, Java, MVVM, Coroutines, Dagger 2, Data Binding, OkHttp, Retrofit

Tasks:
• Chose MVVM as the architecture for the whole project.
• Applied Dagger 2 (for DI) and RxJava 2 (for reactive programming and multithreading).
• Took the lead in shaping the RESTful API endpoints for the client-side while working closely with a back-end developer.
• Reviewed the designs and provided feedback from the UX and Android-specific point of view which resulted in a well-thought end product.
• Conducted basic penetration tests and discovered some security issues.
• Implemented ProGuard to shrink, optimize, and obfuscate code.
• Wrote unit tests and used Mockito and JUnit 4.
• Helped to write instrumental tests using Calabash and Cucumber.
• Used a number of other useful tools such as Retrofit 2, OkHTTP3, Timber, Lombok, Butterknife, Joda-Time, Lottie, and so on.

In a team of 2 Android developers, I developed a beautifully designed application, which was used to easily order insurance packages for Volvo clients.

Apart from developing the app, some of my tasks included also setting up a Bitrise (continuous integration for the project), communicating with a design agency to discuss better usability for Android users, and deploying the app to the Google Play Store.

This is a modern insurance app for Digital Nomads with a very user-friendly process of signing up for new insurance.

One of the main concerns in the project was the security and privacy of the user's data (medical data needed the highest security levels).

As the only Android developer in the project, I was responsible for the whole development, chose the architecture and tools, and shaped the RESTful API endpoints.

This is an application for searching and reserving coworking spaces for Code Control community members.

Tasks:
• Used Firebase (Firestore and authentication) and ContentFull for networking.
• Implemented MVVM architecture with Dagger 2 and RxJava 2 for onboarding.
• Developed the whole application in Kotlin.

This is a complex board game that was successfully translated into a mobile application. It's a game where multiple users play in real-time with one another, send messages, and perform a variety of actions—like buying and using items, attending meetings, and more. The app has a complex graphic design and requires constant data exchanges.

Tasks:
• Led, developed, architected, tested, and managed the entire project remotely.
• Used a Firebase real-time database to manage the app's constant data exchanges.
• Helped and advise the client about user experience (UX) and design in general.

This is an application for managing different types of tools for electricians. It also provides the function of finding the nearest location with tools that an electrician needs.

Tasks:
• Played a crucial role in the entire creation process of the mobile application from the design, development, and testing to the deployment and maintenance.

This is a remote controller for REZAP MODULAR. The application was written in Ionic (a cross-platform framework for mobile app development) and was deployed on Android and iOS platforms.
