United Arab Emirates

Message

At XWave, I architected and built XWave and its digital wallet platform from the ground up, covering the mobile app, backend, database schema, security, infrastructure, and production deployments. I also reduced application load times by over 80% and helped migrate the monolithic codebase to event-driven microservices.

At DevelopLogix, I developed Android and iOS apps, including NFC and BLE features that reduced BLE-related battery consumption by 20–30%. Earlier, at ParityZone, I developed and published Android apps, including Speak & Translate, and increased AdMob revenue by 5–7% across four production apps.
