Summary

I have 14+ years experience with Java and 13+ 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 alongside our studies. Besides that our collaboration continued on our private projects from which a 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 several years of experience already. Here I met Matus Choma and we worked together with passion on multiple projects. My position over time evolved 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.

Nowadays my focus is on creating standards and architectures which are easy to follow for newcomers 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.

For the last year I’ve been actively using and researching AI — it’s now a core part of my development stack and a massive productivity booster that gives me superpowers. I work with Claude Code, Cursor, Gemini, Firebender, and also experiment with local models (Ollama, MLX) which I see as a key security advantage. I always focus on turning repetitive tasks into reusable skills and agent definitions so anyone can pick them up and run with them.

I’m used to working fully independently in remote teams covering the whole cycle. From CI/CD definition, spec definition, implementation, review and dev testing. With AI the one man team per platform is actually perfect setup as there is no synchronization overhead.

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:

It’s my long running hobby to decompile android apps to study how they work and what the weaknesses are. 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 done 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.
