Dear Client, I read "Customize Android Quiz App" carefully and understand you want clean, modern Figma designs that translate smoothly into a real product. My hands-on experience with Java, Mobile App Development, Android, Mobile App Testing, Android App Development aligns directly with what you need. I design in Figma with a focus on usability and visual polish — wireframes, high-fidelity mockups, prototypes and design systems — handed off dev-ready so nothing gets lost in build. A few quick questions to get us started: 1. Is this for a website, mobile app, or both? 2. Do you have existing branding (logo, colors, fonts), or should I help define it? 3. Do you need clickable prototypes, or static screens with a handoff-ready design system? Thanks & Regards, Deepak
