Lead Software Developer at GenAquarius

I build the mobile apps people keep on their home screen.

I'm Gurkaranvir Singh Bambhrah, a Flutter and native mobile developer from India. For more than 11 years I've led teams that take apps from the first requirements call through to release and long-term care, on Android, iOS and the web.

About me

I care about apps that feel fast, stay stable and are easy for the next developer to pick up.

Most of my work is in Flutter and Dart, backed by years of native Android (Java, Kotlin) and iOS (Objective-C, Swift), plus React and Node.js on the web side. I've rewritten whole codebases in Flutter, built custom widgets and tuned state management until interactions feel seamless.

As a lead, I run projects end to end, from gathering requirements with clients to deployment and maintenance, and I mentor developers and interns along the way. Right now I'm learning machine learning, with a focus on on-device models.

    Udaya manages the company's routers and adapters. The WANI apps follow PM-WANI protocols to find and connect to free Wi-Fi nearby. I managed every variant, shipped new features and built the bridge between Flutter and native code.
