Job Success
Bahawalpur, Pakistan - 9:37 am local time
My core specialty is Android POS and fintech systems, with full cross-platform mobile capability.
Most recently, I built and deployed an Android POS & KIOSK system that processed AUD 1.5+ million via Stripe across 100+ devices in 10 days at the Sydney Royal Easter Show 2025 - operating reliably even in poor network conditions.
WHAT MAKES ME DIFFERENT?
I don't just build features. I design systems that survive real-world conditions - then I ship them.
🔹 Android POS & Fintech Systems
Stripe Terminal SDK integration for secure card-present payments
RFID / Smart Card (Fun Card) stored-value integration
Offline SKU caching for low-connectivity environments
Offline transaction queuing with intelligent sync points
Retry mechanisms, reconciliation flows & transaction integrity safeguards
🔹 Mobile & Product Engineering
• Android apps with Kotlin, Jetpack Compose, MVVM, Clean Architecture
• React Native production apps with structured analytics architecture
• Node.js & NestJS backend systems
• Advanced analytics event tracking & attribution systems
• CI/CD pipelines (GitHub Actions, Firebase, Play Store automation)
• Authentication migrations (Clerk, Expo, native integrations)
• Performance optimization & build system stabilization
WHAT I CONSISTENTLY DELIVER FOR CLIENTS:
✔ Production-grade apps launched on tight timelines
✔ Secure, offline-resilient systems
✔ Clean, maintainable codebases built for long-term growth
✔ Clear communication and fast response - avg. response time under 2 hours
If you need a mobile developer who has shipped fintech and POS systems for real, high-traffic events - not just side projects, let's talk. Send me a message and I'll get back to you within a few hours.
