Job Success
Bahawalpur, Pakistan - 6:23 pm local time
I build Native Android, Native iOS, and React Native applications that hold up under real-world pressure: high traffic, unreliable networks, hardware integrations, and tight deadlines.
Most recently: I built and deployed a multi-terminal Android POS & Kiosk system that processed AUD 1.5M+ via Stripe across 100+ devices in 10 days at the Sydney Royal Easter Show 2025 — running reliably in poor network conditions throughout.
That's the standard I hold myself to on every project.
WHAT I BUILD
🔹 Android & iOS Apps — Kotlin, Swift, Jetpack Compose, Clean Architecture, MVVM
🔹 React Native — Production apps with analytics, CI/CD, auth integrations and more
🔹 Payment & Hardware Systems — Stripe Terminal, RFID, BLE, kiosk, POS
🔹 Backend — Node.js, NestJS, REST APIs
🔹 Offline-First Systems — Sync, retry logic, transaction integrity, fault tolerance
WHERE I'VE DELIVERED
💳 Fintech & payment platforms
🛍️ E-commerce & booking apps
🎪 High-traffic event platforms (agenda, networking, AR navigation)
🏭 IoT & hardware-integrated mobile systems
🔐 Access control & identity systems
WHY CLIENTS REHIRE ME
I don't hand off prototypes and disappear. I think in systems, considering edge cases, failure modes, and long-term maintainability before writing line one of code. You get an engineer who cares whether your product actually works in production.
