Summary

I have 13+ years experience with Java and 12+ years with Android development creating over 40 apps. I collaborated with my friend and colleague Marek Richter since university and we worked together as freelancers for multiple companies on many projects along with the study. Besides that our collaboration continued on our private projects from which few were published on Google Play Store and the most popular reached 50 000+ installs. After graduation I started working for company Wirecard GmbH in Košice, with already several years of experience. Here I met Matus Choma and we worked together with passion on multiple projects. My position over time changed into senior lead android architect and I focused mainly on app architectures, configurable and skinnable approach, testing strategy, clean code approach and introduction of new technologies as Retrolambda, RxJava, Stream API, Retrofit and more recently Kotlin, MVI, Dagger.

Now-days my focus is on creating standards and architectures which are easy to follow for new-comers and help with simplification of new development. I see great future in Kotlin Multiplatform approach either with full native UIs (Jetpack Compose and Swift UI) or with shared UI with Compose Multiplatform.

I spend my free time investigating next big thing on Android platform as Kotlin Multiplatform, Kotlin MVI, Redux, Google approach of MVVM and connections to Apple platform as well. I also enjoy open source at: https://github.com/Lighture and random app analyze with code deobfuscation. My hobbies are watching movies, tv series, mtb bike, simracing (Asseto corsa), pc games (GTA 5, Arma 3, 7 days 2 die), psychology, cars.

Ethical hacking:

Its my long running hobby to decompile android apps to study how they work and what are the weakness. This not only helped me to understand what they do wrong but also what I need to do correctly. As security was quite a big topic during my development career I always looked for solutions how to obfuscate code correctly with tools like proguard, dexguard, arxan. I have did small projects on ethical hacking of existing application with code injection to showcase e.g. free -> pro accounts, licences or access of hidden part of the app with .SMALI code injection. Besides that I worked with SQL injection and PHP injections on various web projects.
All of this is currently hobby and done safely without affecting developers, owners of apps and their intellectual property.
