OVERVIEW

Vibranium explored a sports-trading product where athlete performance becomes a live market surface rather than a traditional betting or fantasy flow. The frontend needed to make that idea legible across home discovery, trading, portfolio, leaderboard, and educational surfaces.

I worked across the application frontend, building the main shell, responsive navigation, onboarding and splash flow, athlete detail and trade interfaces, portfolio views, discover tables, leaderboard screens, and learn pages.

A core challenge was turning a speculative product concept into something that felt operational. Dense metrics, charts, tables, search, league switching, wallet prompts, tabs, sliders, and live-event surfaces all had to read as one coherent interface.

WHAT I OWNED
  • -Built the main app shell with sticky header navigation, scrolling market ticker, search, notifications, wallet and balance popovers, and responsive mobile menu patterns.
  • -Implemented the home, discover, leaderboard, portfolio, and learn experiences with reusable cards, tables, charts, filters, and content modules shaped for sports-market workflows.
  • -Built the athlete trading surface across banner state, stats cards, multi-line price chart tabs, index-weight and active-position panels, and a long/short trading panel with order size, leverage, advanced parameters, and trade summary.
  • -Handled onboarding-oriented frontend flows such as splash state, explainer sequence, wallet-connect modal, and route-specific state handoffs so the product felt navigable even before backend integration.
KEY OUTCOMES
  • -Delivered a full multi-page frontend prototype that made the athlete-index trading concept feel substantially more concrete and testable.
  • -Created a consistent interface system across dense product areas including discovery, charting, rankings, portfolio management, learning, and trading actions.
  • -Turned multiple abstract product ideas into usable frontend flows with responsive layouts, clearer hierarchy, and interaction patterns that could support future backend integration.
