Available to hire
I’m Kerem Balaban, a Mobile Architect with 15+ years of experience delivering scalable, high-performance iOS, Android, and React Native apps used by millions. I own mobile architecture end-to-end, lead complex re-architectures, and translate business requirements into clean, maintainable, production-ready mobile systems. I’ve worked across consumer apps, enterprise platforms, and hardware-integrated products, balancing speed, quality, and long-term scalability. In roles at Smart Nora (Canada), Microsoft (Math Solver), and Bundle News, I defined architectural direction, led mobile engineers, and partnered closely with product and design to ship reliable features under real-world constraints. I’m currently open to full-time or long-term contract Senior/Lead/Mobile Architect roles in product-driven teams that value strong engineering culture, ownership, and impact.
