* Implemented mobile banking systems with a focus on data security
* Integrated mobile tokens (Asseco & Entrust tokens)
* Gained experience with both SOAP-based web services and REST APIs
* Implemented MVP architecture on Android
* Used dependency injection with Dagger for easy configuration switching between tests and production code. Motivation: having a central config module where parts of the architectures can be switched with minimal effort
* Conducted acceptance/regression testing with Robotium. Ran tests in parallel with Spoon
* Conducted unit tests with Robolectric
* Created mockups of test data with Mockito and MockWebServer
* Set up Jenkins ontinuous integration server with both GitHub and Bitbucket hooks

* Implemented MojVip (Vip telecommunications network) application, which makes the process of checking your current account balance fast and easy. It enables you to check your current balance, remaining free minutes, and past receipts; buy surf mobile packages; change roaming status; and much more.
* Handles auto-login if you are using the Vip network and are on mobile data connection. Requires authentication over wifi.

* Developed the Android client which operates as a national online classifieds marketplace for used goods, globally active in 100+ countries.
* Defined funnels and implemented analytics
* AB testing
* Participated in the process of creating Android OS images with embedded app to sell on new phones on the eastern markets
* Worked on the project as part of a distributed team. Experienced in working with time difference (better planning)

* Mobile Android game for Samsung Stylus Pen devices where the goal is to navigate the little fish to the end of the level, squeezing through tight obstacles and evading enemies.
* The focus of the development process was on the creativeness, research, and close work with an illustrator. It was really fun.

* Worked on the app for the Croatian auto club

* Experienced in the usage of Balsamiq wireframing tool for quick iterations in defining the client's feature set and design needs
* Experienced in the usage of InVision prototyping tool for setting up real life app prototypes with screen designs

Started an in-house education meetup for exchanging experience from past and current projects. The talks were filmed and broadcast on YouTube and are available at the provided link. Android Talks are regularly featured in Android Weekly, a free newsletter that helps you to stay cutting-edge with your Android development.

* Created the native Android wrapper for the bank mobile web application.

Writing about my travels, psychology topics and my experience in being part of the startup community.

An iOS app for deep analysis of mobile carrier network status that develops in-depth understanding of the carrier's data collected across iOS versions, collects network status info as changes occur, and uploads data to the server for later analysis and visualization. I built the app and created dynamic wizards to navigate the user through a network troubleshooting process. It accommodates a flexible data structure that works regardless of language and adapts the wizard component for different market and language requirements. The app collects mobile network data for better understanding of signal strength and network stability for individual carriers, and the in-app diagnostics help give clients instant feedback on their connection status and steps they can take to resolve issues, thus diminishing pressure on support call centers.

An Android app built for deep analysis of mobile carrier network status that develops in-depth understanding of the carrier's data collected across Android versions, collects network status info when changes occur, and collects and stores data locally to upload when a WiFi connection is available. I built the app and created smart retry mechanisms to upload data in chunks in case a large amount of data is collected over a prolonged period of network non-availability. I also created dynamic wizards to navigate the user through a network troubleshooting process. The wizard accommodates a flexible, adaptable data structure that works regardless of market and language requirements.
