Mobile software engineer at Stoneslane who sped up Masdary responses to 300ms with offline-first caching.

Ethiopia

Message

At Stoneslane, I work on Masdary, an Arabic- and English-language e-commerce app. I improved its response time from about two seconds to 300ms with local-first ObjectBox caching and background Firestore sync, and reduced FPS drops by 28% through rendering optimizations.

I’ve also built reusable Flutter packages, added Firebase Crashlytics reporting, and contributed to a Flutter and TypeScript super app. Earlier, I led mobile development at Eskalate, where I implemented Clean Architecture and enabled offline and online support.
