Senior Mobile Engineer

Senior Mobile Engineer with over 8 years of experience building and scaling mobile applications across Android, Flutter, and iOS. Throughout my career, I have delivered products in e-commerce, logistics, education, digital invitations, and seller management, with several applications serving millions of users. I specialize in mobile architecture, native Android (Kotlin/Java), Flutter, iOS integration, performance optimization, and scalable cross-platform development. From leading native-to-Flutter migrations and optimizing application startup performance to designing offline-first architectures and CI/CD pipelines, I focus on delivering robust, maintainable, and high-quality mobile solutions. Beyond writing code, I enjoy leading technical initiatives, mentoring engineers, driving architectural decisions, and collaborating across teams to build mobile products that create meaningful business impact.
