About Me

iOS engineer with 5+ years building on the Apple platform — from Swift and SwiftUI to Objective-C and UIKit. I've led iOS cohorts, shipped SDK integrations across native and cross-platform stacks, and driven quality on device OS software at Amazon. I care about ownership, clean architecture, and shipping software that works.

Currently at Grabba integrating mobile SDKs across iOS and Android. Looking for a Senior iOS Engineer role where I can drive architecture decisions, mentor engineers, and build great user-facing experiences.
