What I'm looking for

I'm looking to own mobile architecture for connected products, especially where React Native, BLE, cloud and hardware meet, while helping remote teams ship reliably through strong engineering foundations.

At Dometic, I owned the mobile architecture for connected cooling, climate and power products, linking React Native apps to smart hardware over BLE and cloud. I rebuilt legacy apps into modular foundations and created GitHub Actions and Fastlane release pipelines that removed manual release errors.

I've led and mentored a distributed frontend team, solved BLE connectivity bottlenecks, and built an ESP32 device-signal emulator for hardware-free testing. Earlier, I launched an OCPP EV-charging system and spent nearly a decade delivering industrial automation, PLC/SCADA and robotics solutions across Europe.
