About Me


I'm currently crafting Python projects and Flutter apps using Dart. I also possess some experience with design tools like Figma, GIMP, and Krita. To further sharpen my programming skills, I actively challenge myself with code problems on CodeWars, where I hold a 4kyu rank. My most successful app boasts over 160,000 downloads.


My time living and working in Ireland further strengthened my English skills, which were already well-developed beforehand. I'm expanding my language repertoire by learning German and maintaining a 1000+ day streak on Duolingo. Currently studying for the CEFR B2 level certificate.


Beyond coding, I've discovered a passion for endurance sports, starting in November 2023. Since then, I've logged over 1000km, dramatically improving my pace from an initial 7:32 min/km. My current best for 10km and above is 4:29 min/km, and I've hit paces of 4:08 min/km for distances under 10km. My achievements include completing multiple uphill 10k races, several half-marathons, a Spartan Super Race in Poland, and conquering a full marathon (42.195km). I am now training for an Ironman 70.3.

Apps

I have developed a lot of apps, 4 of which are published on the Google Play Store and on the Apple App Store. My most notable projects are listed below with additional information about their development and release.

Ysty Style


The app is called “Ysty Style: German grammar for Hungarians”. It is an educational German language learning app. The android version has more than a 100 000+ downloads with more than a 1000+ positive review.


In High School I started writing the Android app in Java. Later I switched to Flutter (Dart language). For monetization I used Admob and Firebase for Database. Currently the iOS version is behind compared to the Android app, but I am already working on it.
