- Senior Mobile Application Engineer with 9+ years of hands-on experience delivering Android, iOS, and Flutter applications used in real production environments.
- Strong expertise in Flutter cross-platform development, backed by deep native Android (Java/Kotlin) and iOS (Swift) experience.
- Proven track record in clean architecture, offline-first systems, real-time communication, and enterprise-grade mobile solutions.
- Experienced in technical leadership, architecture ownership, and modernizing legacy mobile applications into scalable systems.
I’m a mobile engineer who focuses on long-term maintainability, clean design, and production reality rather than quick demos.
Over the years, I’ve worked on enterprise and consumer applications involving real-time dashboards, secure authentication, location-based services, offline data synchronization, and large-scale user bases. I’ve led mobile initiatives from architecture to release, collaborating closely with backend, product, and UX teams.
