Rockstar🎓
Top SchoolPetrus Nguyen is a Senior Android Software Engineer based in Da Nang, Vietnam with eight years of mobile-first experience across Android, iOS and Flutter. He combines practical app engineering with a strong functional and reactive programming focus—an active contributor to well-known open-source projects like Arrow (Kotlin) and rxdart, where he implemented operators, fixed tricky concurrency/resource bugs, and improved testability. At SUPREMETECH he progressed from Android Engineer to Senior Android Software Engineer, delivering domain-driven back-end integrations and clean architecture on mobile platforms. He has hands-on experience building data layers, use cases, and remote APIs, and is comfortable across Kotlin Coroutines/Flow, Rx family libraries, and cross-platform stacks. Notably, his open-source work shows attention to subtle correctness and resource management issues that often surface only in mature, concurrent codebases.
