Senior iOS Engineer with over 10 years of experience helping companies build robust, scalable, and production-ready mobile applications. I bring a rare combination of deep technical insight and business acumen, enabling me to not only develop software but also make strategic decisions that directly impact the product and bottom line.
I have led the development of fintech, banking, POS, and IoT apps, creating products from scratch, managing development teams, and defining scalable and secure architectures. I work with Swift, modern architectures, complex API integrations, and payment systems, always focusing on performance, maintainability, and user experience.
I typically manage projects end-to-end: technical definition, planning, team leadership, code reviews, performance optimization, backend integration, and App Store publication. I differentiate myself through my ability to combine high-level technical execution with leadership and strategic product vision.
