About
Engineer for product teams that ship.
I work across the full mobile delivery cycle: architecture, UI, IoT integration, API communication, app security, testing, deployments, and team execution. My recent work focuses on connected security products where reliability, smooth onboarding, and safe device communication matter.
Performance
Improved launch and runtime performance by 32% through profiling, Kotlin optimization, and image caching.
Quality
Raised unit test coverage by 24% and led code quality improvements across mobile teams.
Delivery
Owned Android and iOS deployment workflows across signing, certificates, Play Console, and TestFlight tracks.
Technical Stack
Mobile, platform, and connected-device skills.
A resume website should make scanning easy. These groups mirror how mobile product teams usually evaluate fit.
