About me
My journey blends a strong foundation in physics with a passion for building robust software solutions in complex domains. After earning my Master of Science in Physics from Budapest University of Technology and Economics in 2002, I spent the early years writing high-performance C++ for industrial automation and embedded systems. Since 2016 I’ve worked as an independent freelancer, architecting end-to-end solutions that combine embedded firmware, IoT backends, and modern user interfaces.
I specialize in clean, maintainable architectures (Domain-Driven Design, Model-Based Systems Engineering) and in choosing the right tool for the job.
I'm also proud to be recognized within the top 10% of contributors on the Nordic DevZone, showcasing my expertise in embedded systems.
In the past three years my focus has shifted strongly toward the Kotlin ecosystem. I have delivered production Android applications with Jetpack Compose and, most recently, I’ve gone full Kotlin Multiplatform: my latest project is a real-time Pose Landmarker app that runs with identical business logic and Decompose-based navigation on both Android and iOS (see https://github.com/PopradiArpad/PoseDetector).
I now consider KMP + Compose Multiplatform + Decompose my primary stack for any new mobile or cross-platform project.
I’m actively looking for new remote contracts in the Kotlin Multiplatform space — whether pure Android, full Android + iOS shared codebases, or desktop extensions.
If you need someone who can design, ship, and maintain a single Kotlin codebase that delivers native performance and native UX on every platform, let’s talk.
