ČSOB SmartBanking

One of the first mobile banking applications on the Slovak market. Apart from obligatory base features such as payments, transaction history, or account dashboard, SmartBanking offers users a variety of exciting features; fund investments, public transport ticket purchase, or insurance contracts of various types such as travel and car insurance.

It has been the highest-rated mobile banking app on Google Play Store from all Slovak banking applications for a few months.

I worked as a senior Android developer on this project, and I had implemented the aforementioned public-transport-ticket-purchase feature using PostMessage API, language localization feature, or an online authorization method for payments and logins to the internet banking.

In addition, I streamlined and divided the building process to separate build flavors for Huawei and Google mobile services. I also implemented a dependency check Gradle plugin which scans projects dependencies and checks for possible vulnerabilities.

eZóna SSE

A Kotlin-based Android application offering users the possibility to track their utility consumption, list and pay invoices, contact the provider, and more.

I was the lead Android developer. As such, my job was to work closely with other teams, especially the analytical team. Furthermore, my responsibilities were to implement and maintain a proper project infrastructure as well as a high-quality codebase that is sustainable and scalable.
