At Yassir, I build features for a super app serving millions across ride booking, food delivery, marketplace, ticketing, and payments. I led a unified authentication solution across the Super App, Driver, Courier, and Store apps, and helped unify YassirExpress and YassirRider.
I work across 17+ Swift packages using Tuist, SPM, MVVM, SwiftUI, and UIKit. I’m driving Swift 6 strict concurrency migration with async/await, actor isolation, and Sendable conformance while maintaining feature delivery.
Previously, I built real-time reactions, polls, and quizzes for SportBuff’s live-sports SDK, with Objective-C compatibility and a React Native demo for adoption. At Safaricom’s DigiFarm, I helped launch financial services reaching 50,000 farmers and introduced feature flags that accelerated delivery by 12%.
I care about reliable releases, modular quality, and practical developer tooling. My delivered Yassir modules reached 90% unit test coverage, and I actively evaluate AI tooling including Claude Code and Codex in Xcode.
