  • Home Unit and MyTCare apps As the Android developer I've been working simultaneously on two apps intended for elderly care. Being the only developer in the projects I've been performing both the engineering and lead functions. Starting from scratch, I applied the MVVM architecture in Kotlin for both the apps, sticking to the single-activity approach and utilising LiveData, coroutines, the Jetpack's navigation component and Dagger. • S-mobiili app Worked as the Android developer on the app intended for banking, financial management, trade services and insurance. Using Kotlin, I developed such app features as bonus for purchases, places of business (bonus locations), purchase receipts, messages and feedback services, authentication with the 3rd party bank credentials. I modularized 25 % of the app features. Following the VIPER architecture, each feature was divided into seven modules, giving 130 modules overall. Publishing the modules as artifacts to JFrog Artifactory decreased the build time 3 times. The team achieved 70% automated test coverage, using a combination of Mockito and Espresso. The time pressures for delivery were very tight. We didn’t have time to refactor for more than a year. Adding more features to the app resulted in a greater build time due to increased amount of the auto-generated code brought by Dagger and data binding. For 350 Fragments the build time took up to 15 mins locally and 40 mins remotely on Jenkins. It made me uncomfortable to be working that way as it was slowing down both the development and delivery. As said, the problem was solved by the modularization and artifacts publishing, however not having the app features modularized in advance was a mistake. • Kungliga Operan app As the Android developer I worked on the app for the Royal Swedish Opera used for presenting the opera repertoire and providing the text/audio description synchronized with the performance. Using Java, I developed the extended accessibility functionality. Show less

  I worked as the Junior Android developer on an app for a new generation of the ballot scanners used in the state and regional elections. Despite the Junior position I was leading a team of 3 developers. In Java, I implemented the state machine app architecture, developed the library for network services registration/discovery using UDP and TCP/IP communication of the discovered devices as well as the text pagination functionality required for composing multi-page election reports. We were time constrained for delivery and had to cut corners, meaning we didn’t have unit tests. Even though we met the business demands, not having unit tests was a mistake as I didn’t know the quality of my code. Show less

  I worked on the Matlab/Simulink app for modeling and simulation of the fluid steady-state and transient behaviours in oil pipeline leak detection systems. The Matlab app was used as prototype for development of the C++ app the company delivered for real-time leak detection systems. This was my 2nd full-time job at the time. Being the only developer, I started with extending the functionality of the app, namely, I developed the T-junction pipeline element intended for connection of 3 pipes. It allowed modeling complex pipeline by dividing and combining the flows in it. Working with the app code I came to the conclusion that it was hard to extend and maintain, its readability left something to be desired. Moreover, investigating the other numerical methods that could be applied I found the used method to be outdated. When my suggestion to apply a new numerical method to all the pipeline elements was accepted, I developed the new app version. I refactored more than 85% of code reducing its overall amount 3 times. The C++ "analog" of the new version gave at least 4 times faster processing time which was a crucial improvement taking into account its real-time flavor. Show less
