Mobile systems, integrations, and operational software
I'm a Mobile Specialist with experience building Android applications, operational systems, IoT integrations, and software that communicates with real-world devices.
My work spans the full mobile system: user interfaces, application architecture, APIs, background services, local data, hardware communication, and backend integration.
I enjoy solving problems where mobile applications become part of a larger operational system, not just standalone apps.
