Syed Rizwan

Led the end-to-end mobile development lifecycle for 20+ iOS, Android, and cross-platform client and product applications, covering architecture, delivery, store releases, and production support. Built real-estate and customer apps (voice/video tours, valuations, lead routing, messaging, and notifications) supporting weekly conversions, and delivered live-video commerce features that improved sales, cart size, and reduced returns. Owned mobile delivery for a school platform reaching 100+ schools, 6,500+ teachers, and 100,000+ students, and contributed to an e-commerce app reaching 100,000 downloads in Saudi Arabia. Implemented monetization using subscriptions, in-app purchases, Stripe/PayPal, and wallet integrations with secure payment flows. Used Firebase Analytics/Crashlytics and performance monitoring, built/maintained offline-capable experiences, and owned comprehensive testing, CI/CD, release readiness, code reviews, mentoring, and incident support.

Improved shared architecture and reusable mobile components across two healthcare applications, strengthening reliability, privacy, and maintainability for clinical workflows. Built native iOS functionality using Swift/Objective-C, UIKit, MVVM, Core Data, and robust local persistence and caching. Integrated third-party platforms (Twilio, QuickBlox, Nuance, Foxit) to deliver chat, video, voice-recognition, appointment, and PDF workflow features. Analyzed crashes, memory/network performance, and device/OS behavior to improve stability under real-world network conditions; supported unit/UI/integration testing, signing, App Store builds, deployment, post-release monitoring, and cross-functional delivery.

Architected and shipped native iPhone and Android applications through design, implementation, testing, store releases, production updates, and long-term maintenance. Led small engineering teams (2–5) while staying hands-on with Objective-C/Swift and Java/UIKit, Core Data/SQLite, networking, payments, notifications, synchronization, device APIs, and performance profiling. Coordinated architecture decisions, code reviews, estimates, signing, release execution, defect resolution, documentation, and mentoring across concurrent mobile projects.
