What I'm looking for

I'm looking to build scalable mobile products where I can combine React Native, cloud architecture, CI/CD automation, AI integrations, and reliable user-focused features.

I've built React Native applications at Acuity Software Services, including BLE-enabled IoT solutions with device discovery, GATT communication, MQTT telemetry, and AWS IoT Core synchronization.

I developed a full-stack mobile application using Gemini Vision API, Firebase Phone Authentication, PostgreSQL, EventBridge, Lambda, SQS, and WhatsApp Business Cloud API to support product recognition, expiry tracking, and automated reminders. I also optimized prompt engineering and token usage, reducing monthly AI billing by 46%.

At Indware Technologies, I delivered mobile features such as POS thermal-printer support, REST and GraphQL integrations, push notifications, deep linking, offline SQLite storage, secure authentication, and interactive Expo interfaces.

I've automated Android and iOS delivery through GitLab, Fastlane, Firebase App Distribution, Detox testing, and CI/CD pipelines while troubleshooting cross-platform React Native compatibility issues.
