What I'm looking for

I'm seeking roles building privacy-focused on-device AI and performant mobile systems, with opportunities to own architecture, ship production apps, and improve CI/CD and runtime performance.

I build privacy-first, low-latency Android AI systems and production apps, specializing in on-device ML (TensorFlow Lite, ONNX Runtime, Whisper) and performant mobile pipelines using Kotlin and Jetpack Compose. I've shipped multiple Play Store apps and delivered production features across freelance and internship roles.

At NeuroV I lead development of an offline AI assistant with sub-200 ms interaction times, a dynamic plugin framework, NL→JSON command execution, C++/JNI bridges, and CI automation that cut manual release operations by ~60%. I also delivered user modules, migrated legacy Java to modern Jetpack components, and reduced ANRs through architecture cleanup during internships.

My engineering approach blends systems-level work (C++/JNI, plugin runtimes, AIDL) with modern Android architecture (MVVM, Coroutines/Flow, Hilt, RoomDB), emphasizing privacy, deterministic outputs, and maintainable CI/CD practices. I'm motivated to build robust, efficient mobile AI experiences that scale to real users.
