Zaid Mubbasher

I've shipped production mobile and web software across fintech, banking, IoT, e-commerce, and enterprise SaaS for Devflovv, Barq Fintech, Techificent, and UBL Bank. At Devflovv, I lead engineering for KēZ (KeyFree), a live App Store connected-vehicle app, delivering OAuth and biometric login, secure sessions, push notifications, BLE/MQTT integration, SSL pinning, and Fastlane CI/CD. I also contribute to Streamline SaaS with real-time messaging, WebRTC/VoIP calling, calendar, and issue tracking. For UBL Tezraftaar, I spent three years building security-sensitive banking features, integrating transactional REST APIs and creating offline-first CoreData sync with Clean Architecture and MVVM. Alongside full-time work, I've shipped React Native apps to the App Store and Play Store and built React/Node.js SaaS platforms, WordPress products, WooCommerce stores, and tailored client solutions. I enjoy owning delivery end to end, from architecture and design through release, support, reviews, and mentoring.
