Excited to share Sandbox, my submission for the #FlowstepChallenge 🚀

Sandbox is a mobile platform where startups and students can build in public, showcase real projects, discover opportunities, and form meaningful professional connections.

For this submission, I focused on the startup experience and designed an interactive prototype in @flowstep_ai, covering onboarding, authentication, the home feed, Explore, startup dashboard, project and applicant management, leaderboards, profiles, search, and notifications.

Instead of traditional social-media engagement, Sandbox introduces more meaningful interactions:

Posts build visibility. Projects build credibility. Upraises build reputation.

Most social platforms reward attention. Sandbox rewards ambition.

Built and refined directly inside Flowstep, with a focus on consistent components, connected navigation, reusable UI patterns, and a professional mobile experience.
