Mobile Engineer with over four years of professional experience building and maintaining production mobile applications for Android and iOS, currently running on more than 25,000 devices. My work is primarily focused on React Native, complemented by hands-on native integration work in Kotlin and Swift when platform-level solutions are required.
I have worked on systems where reliability, performance and long-term maintainability were critical: hardware-integrated applications for industrial sensors, an official nature app for the Bavarian Ministry for the Environment, map-heavy interfaces rendering 10,000+ points of interest, and a full-stack public utility platform.
I'm experienced in working within real-world constraints - unstable connections, offline scenarios, performance bottlenecks and evolving product requirements - while keeping systems predictable and maintainable over time. The offline-first sync architecture I designed has recorded zero data-loss incidents across all field deployments.
Leading the technical direction of three concurrent React Native products - industrial IoT, public utilities and geo-navigation - from system design through App Store and Google Play release. Established code review standards, branching strategy and release processes that cut emergency hotfix deployments by roughly 40% within six months. Mentoring junior developers, conducting technical interviews, and serving as primary technical contact for enterprise clients in Germany and Hungary.
Shipped four production React Native apps to the App Store and Google Play, collectively reaching 25,000+ active devices across industrial and public-sector clients. Built a custom native communication layer (Kotlin/Swift) for industrial sensors using BLE and Bluetooth Classic protocols that no existing React Native library supported. Implemented native geofencing with background-location tuning that reduced battery drain by ~35%.
Started as a web developer building production frontend applications with React and Next.js for content-driven platforms. Taught myself React Native outside assigned work and proposed expanding the studio's mobile capability - which led to a formal role change within 12 months.
