Hi, I'm Roger

I’m a Mobile App Developer with 15+ years of experience building high-quality iOS and cross-platform applications.

Since 2017, I’ve partnered with numerous startups and SMEs to turn their ideas into successful, scalable digital products — taking them from concept and solid architecture all the way to a polished, market-ready MVP.


What I specialize in:

Native iOS Development — Clean, maintainable Swift & SwiftUI code using strong architectures (MVVM, Clean Architecture, etc.)

Cross-platform solutions with React Native and Ionic — delivering fast, cost-effective mobile and web apps

Rapid MVP Development for startups — I focus on shipping functional products quickly while ensuring long-term scalability and maintainability

Core architecture, performance optimization, third-party integrations (Maps, Calendars, Live Activities, etc.), and apps built to grow

I’ve worked alongside talented engineers and founders with prior experience at leading tech companies including Microsoft, Google, Twitter (X), Spotify, and Instagram.

Whether you need a modern native iOS app, a React Native / Ionic hybrid solution, or a lean MVP to validate your idea — I help you move fast without cutting corners on quality.
