Production Android, from payment rails to living-room robots.

Evolve consumer payment features inside one of the world's largest payments apps — where reliability, correctness, and performance are non-negotiable and the codebase is massive.

Production Android features in Kotlin with Jetpack components and modern architecture — shipping Jetpack Compose UI, orchestrating reliable background work with WorkManager & Job Scheduler, and building reactive flows with Coroutines & Flow against existing components and REST APIs.

Miko's companion robot for kids needed a polished, safe, parent-facing Android app that talks to the robot in real time, serves rich learning content, and keeps families engaged.

Led Android development in Kotlin/MVVM — AIDL-based IPC to coordinate with the robot's services, responsive Jetpack Compose UIs, and background/async pipelines with WorkManager, Coroutines, Flow & RxJava. Integrated Maps, Camera, Location and REST APIs, and shipped Flutter builds for reach.

Onboard telecom customers in minutes with a compliant, on-device digital KYC flow — verifying documents and faces reliably across a huge range of Android phones.

An internal Android SDK that streamlined cellular onboarding & KYC automation — integrating TensorFlow models with Camera/Camera2/CameraX for on-device image processing, bridging native code via JNI, and wiring networking with Retrofit/OkHttp. Shipped in JioPOS Plus, with CircleCI CI.

Small merchants needed a fast, offline-friendly point-of-sale and online shopfront on Android — scan or search items, bill in seconds, and print or share receipts.

The Android POS and online shopfront in Kotlin/MVVM — optimized Gradle builds, a multi-module architecture, and legacy code refactored to MVVM. Integrated Location, Wi-Fi, GPS, Camera, and Bluetooth receipt printing, plus a Flutter build.

Bring prayer, Quran, duas, community chat, giving, and a marketplace into one accessible Android app — easy enough for everyone in the family to use.

Shopping- and accessibility-focused Android in Kotlin/MVVM with Jetpack Architecture Components — a multi-module architecture with Room, LiveData, ViewModel & Paging, REST & GraphQL, and Location services for nearby-agent discovery and communication workflows.

Give citizens and city teams a way to track bins, waste pickups, and green workers across localities — and nudge better waste-segregation habits.

IoT-based Android apps in Java/MVP — integrated the Firebase suite (Realtime DB, Auth, Storage, Remote Config, Crashlytics, Cloud Functions), geofencing & Google Maps, and Bluetooth/Wi-Fi sensors talking to IoT devices, with SQLite persistence.
