What I'm looking for

I'm open to remote or relocation opportunities where I can lead iOS, mobile, backend, or platform architecture, build compliant production systems, and mentor distributed engineering teams.

I've led iOS architecture for a consumer wellness app in SwiftUI and SwiftData, delivering subscription monetization with RevenueCat, privacy-focused Supabase data design, Claude API integration, and the App Store release lifecycle. Previously, I built React Native-to-Swift bridges and production iOS features for an aeronautics startup operating under strict compliance and certification constraints.

Across Santex, ioet, and ThoughtWorks, I've delivered Python microservices, React and Node.js applications, AWS and Kubernetes platforms, and security-focused infrastructure. I've led teams of up to seven engineers, owned architecture and stakeholder communication, mentored engineers, and worked remotely with US teams for more than a decade.
