How can I help You

Native Android Development (Kotlin & Java)

My deepest expertise is in native Android — from architecting MVVM/MVI apps with Jetpack and Hilt to integrating complex hardware like RFID readers, Stripe Terminal (Tap-to-Pay), Bluetooth LE, and serial UART peripherals. I've shipped apps used at high-traffic events that processed over 1.5 million AUD in transactions across 100+ devices in under 10 days.

Cross-Platform Mobile (React Native & KMM)

I build and maintain cross-platform mobile applications using React Native and Kotlin Multiplatform, enabling shared business logic and faster delivery across Android and iOS without sacrificing native performance. I've contributed to full migrations from native codebases to React Native for consumer-facing platforms.

Fintech, POS & Hardware Integration

I specialize in fintech-grade mobile solutions — POS systems, payment gateways (Stripe, Google Pay), offline-first transaction queuing, and hardware integrations (RFID, NFC, card readers). I've built enterprise POS terminals from scratch for retail and events across Australia and the UAE.

Community, Social & Event Applications

I've developed feature-rich event and community apps for international conferences in Dubai, KSA, and beyond — including AR venue navigation, networking features, live polling, real-time chat (QuickBlox, SendBird), push notifications, and admin CMS dashboards for non-technical teams.

Backend & API Development (Node.js)

I complement mobile work with solid backend capabilities — building RESTful APIs and GraphQL services using Node.js, Express, Hasura, and Strapi, deployed on AWS and Heroku — enabling full end-to-end delivery without needing a separate backend developer.
