What I'm looking for

A senior or lead mobile role on a product team that ships: native Android (Kotlin, Compose), iOS (Swift), KMP or Flutter. I do best owning stability, releases and architecture on an app real users depend on. Fully remote, full-time or long-term contract, with some overlap with US or European hours.

Senior mobile developer with 13 years of experience, mostly remote, for teams in the US, Europe and the Middle East. Deepest in native Android (Kotlin, Jetpack Compose; Google Certified), with production iOS (Swift, SwiftUI), Flutter, React Native and Kotlin Multiplatform experience.

Teams usually bring me in to take over unstable codebases and unblock stuck releases. At Portal I published the multi-module Android SDK to Maven Central, which the in-house team had not managed. At Yahoo Sports I owned stability for the Daily Fantasy module and reduced crash and ANR rates release over release. At SKEDit I rebuilt a broken CI/CD pipeline and shipped 10+ production releases in 3 months.

Today I work on Carewell’s Flutter healthcare marketplace (Android and iOS), where I rebuilt the Android release pipeline and created the iOS one. I also build and ship my own Android and iOS apps (pingappslab.com). Open to full-time or contract remote roles, available immediately.
