Android Social App UI/UX Design

I am building a social-networking Android application and need an experienced UI/UX designer to shape the whole user journey—from the very first splash screen to the tiniest micro-interaction. Core experience I’m asking you to craft: • A clean onboarding that guides new members straight into creating rich User Profiles. • A dynamic News Feed that supports text, image, and video posts and keeps users scrolling effortlessly. • Seamless in-feed video playback with intuitive controls. • Threaded conversations that let users dive deep into discussions without feeling lost. • Light, casual in-app Games or interactive elements that spark repeat visits. I’d like the flows mapped in Figma (or a comparable tool you prefer) and delivered as: 1. Low-fidelity wireframes for quick validation. 2. High-fidelity screens following Material Design principles. 3. An interactive prototype showing key paths—onboarding, profile edit, posting to the feed, opening a thread, launching a game. 4. A reusable style guide / UI kit (colors, typography, components, icon set). The design should feel modern, colourful yet uncluttered, and must scale gracefully across common Android resolutions. If this sounds like your sweet spot, tell me how you would tackle the News Feed and threaded comment UX, share a relevant portfolio link, and include an estimated turnaround for the first clickable prototype.
