Senior iOS and Mobile Engineer with over 8 years of experience building production applications across Europe and North America. I specialize in developing scalable, native iOS platforms end-to-end, bridging the gap between sophisticated mobile interfaces and robust backend architectures. My technical foundation is rooted in Swift, SwiftUI, and modern concurrency , with a strong focus on modernizing legacy codebases into clean, MVVM, and reactive architectures (Combine, RxSwift). Beyond the frontend, I bring a "T-shaped" skill set with experience architecting distributed backend systems using FastAPI, PostgreSQL, and Redis. This allows me to design holistic solutions that are performant from the database down to the device. I am particularly passionate about building location-based applications, integrating AR capabilities, and prioritizing native, on-device AI processing to maximize user privacy and reduce cloud dependencies. Currently, I am independently developing consumer products, including an AR-powered utility with custom subscription models and a geographically triggered networking platform. Whether it is improving CI/CD pipelines , mentoring cross-functional teams, or driving the technical direction of a product, I focus on delivering measurable business value. I am currently holding EU work authorization and am actively seeking Senior Mobile Engineering roles, with a strong interest in relocating within the EU market and Turkey or remote opportunities within the EU and Turkey. 1.
