Summary
🤩
Rockstar🎓
Top SchoolClaus Rørbech is a Senior SDK Developer based in Copenhagen with 8+ years of professional experience building mobile and native integrations across Kotlin, Android and embedded Linux. He has driven Kotlin multiplatform and compiler-plugin work at MongoDB for Realm, contributed JNI BSON protocols to the prominent realm-java project, and now focuses on SDK development at Softpay. His background spans low-level C/C++ native integration, Gradle and CI tooling, Bluetooth LE and power management on resource-constrained devices, giving him rare cross-domain fluency from firmware to high-level SDKs. Claus pairs deep systems knowledge with pragmatic developer tooling expertise—often implementing build and interop layers (Swig, cinterop, Gradle plugins) that make complex native features consumable by application teams. Colleagues rely on him for bridging compiler, runtime and platform gaps to deliver reliable sync and data handling for mobile apps. He holds an M.Sc. in Computer Science from the University of Copenhagen.
