Hi, I'm
Building production mobile apps that work reliably in the real world - 25,000+ devices across industrial, public-utility and government services.
I'm a Mobile Engineer working primarily with React Native on production applications used in demanding real-world environments - industrial hardware, public utilities and government services. My work currently runs on more than 25,000 devices.
Much of my work involves features that must function reliably under non-ideal conditions: unstable networks, offline usage, hardware integrations and complex state flows. The offline-first sync architecture I designed has recorded zero data-loss incidents across all field deployments since launch.
I focus on writing clear, predictable code and designing systems that remain maintainable as applications grow over time.
Production mobile applications built under real-world constraints
Natur Digital
Official nature & hiking app of the Bavarian Ministry for the Environment (Germany) - 20,000+ installs. Interactive offline maps with native geofencing and proximity notifications.
Rendering 10,000+ map points of interest without performance degradation on mid-range Android devices.
IMKO Connect
Measurement data collection from professional industrial sensors, using a custom Bluetooth communication layer built natively in Kotlin and Swift. The app works exclusively with IMKO's hardware - every install is an active industrial customer in the field.
Native Bluetooth (Classic & BLE) layer for reliable offline data transfer.
Vodovod Subotica
Utility services platform for a public water company: meter readings, billing and issue reporting, with an internal dashboard for employee and customer management. Sole engineer across mobile, web and backend.
Data consistency across mobile, web and backend, including payment flows with idempotent retry handling (in integration with bank and payment processor ahead of launch).
Hello Vajdaság
Regional tourism app for Vojvodina aggregating events, accommodations and points of interest, with time-sensitive content visibility and fast search (Typesense).
Keeping frequently changing event data accurate - expired content removed automatically, updates consistent across mobile and backend.
Primarily focused on mobile development with React Native, supported by web and backend technologies
