Over deze freelancer

I build mobile apps that work—reliably, intuitively, and at scale.With 15+ years focused on native iOS development and three years building Android apps, I help startups, cultural institutions, and enterprise teams ship products that users trust and businesses depend on. I've architected apps from concept to App Store, modernized legacy codebases, and built cross-platform solutions that don't compromise on quality.

What I Bring to Teams

I specialize in turning complex requirements into polished, production-ready apps. Whether it's greenfield development or inheriting an existing codebase, I prioritize:* Clean architecture* Thorough testing* Sustainable code that teams can maintain and scale.I've implemented Kotlin Multiplatform to share business logic across iOS and Android while preserving fully native UI, cutting feature development time without sacrificing performance or user experience.

Technical Foundation

* iOS has been my core focus since 2011—Swift, SwiftUI, UIKit, and the full ecosystem of tools for building accessible, performant apps.* Since 2022, I've been equally hands-on with Android development in Kotlin and Java, including migrating legacy code and establishing modern patterns.Beyond mobile, I've worked across the stack: backend APIs, web frontends, hardware integrations (Bluetooth, iBeacons, IoT), and voice platforms like Alexa. This diverse foundation empowers me to strategize solutions from multiple angles and align priorities seamlessly with product, design, and backend colleagues.

How I Work

I excel in environments where clarity and delivery matter. I scope work realistically, communicate proactively, and ship on schedule. Whether partnering with a two-person startup or integrating with enterprise processes, I adapt quickly and focus on outcomes that move the business forward.

Looking forward to seeing what we can build together
