About

As a passionate (and a bit nerdy) Android Developer I build robust, maintainable, secure and user-focused Android apps mainly with Clean Architecture, MVVM/MVI, tried and tested design patterns and Domain-Driven Design (DDD). I work by the following mantras: 🏠 Architecture Matters: I design apps using modular, well-structured layers, following SOLID principles to build software that is easy to extend and refactor. 🧹 Code Quality First: Writing readable, testable, and reusable code is one of my main mottos. I embrace Kotlin best practices, Jetpack Compose, and modern Android tools to deliver top-quality applications. 👔 Domain-Driven Design: I ensure business logic remains at the heart of development, leading to software that truly aligns with user needs and business goals. 🏀 Team Player First: I believe in knowledge-sharing, mentorship, and fostering a culture of continuous improvement. Whether through code reviews, pair programming, or open discussions, I’m always eager to learn from and support my teammates. Oh, and having a coffee together does way more than we tend to think! If you’re looking for an Android engineer who values quality, user satisfaction and business success, let’s connect! 🚀
