What I'm looking for

I’m open to remote opportunities and visa-sponsored relocation, and I want to keep shipping production cross-platform mobile features end-to-end—especially with Kotlin Multiplatform, Jetpack Compose, and SwiftUI.

I’m a Senior Mobile Engineer with 5+ years shipping production Kotlin Multiplatform (KMP) applications across iOS and Android. I’ve owned features end-to-end across both native platforms, bridging React Native into existing native codebases when it adds leverage.

At Grey Finance, I drove the flagship fintech app’s Play Store rating from below 3★ to ~4★ by shipping high-impact features and stability fixes. I also designed and maintained a reusable KMP core SDK shared across iOS and Android, encapsulating business logic and Ktor-based networking while eliminating duplicated platform code.

At Cavista, I designed internal Android SDKs adopted by health-tech teams, reducing feature development time by 20% and cutting customer-reported issues by 35%. I built deep-linking infrastructure, delivered clinician-facing workflows with shared business logic, and improved test coverage by ~30% by automating UI testing with the Robot Pattern.
