Real Time Systems
I am a Senior Mobile Engineer focused on scalable architecture, reliability, and long term maintainability. My work spans cross platform mobile systems, backend services, and native integrations where performance and stability matter.
I have led production React Native applications used by tens of thousands of users, rebuilt legacy Android systems into modular architectures, and shipped secure subscription, authentication, and cloud native infrastructure.
I approach engineering with a systems mindset: clear boundaries, measurable performance, defensive error handling, and operational readiness for regulated or data sensitive environments.
