Frontend engineer · Indie app developer · AI-assisted builder

Liang Cheng / Liang Feifan Ray

I turn product ideas into shipped apps with Flutter, SwiftUI, React, TypeScript, and AI-assisted development workflows.

My flagship product is Roam Focus, an App Store app that turns focus time into real map journeys. Born in Haimen, Nantong, Jiangsu. Based in Nanjing. IELTS 7.5, fluent in English for work and communication.

Open to conversations around indie products, frontend engineering, app development, and AI-assisted development workflows.
