The problem

A fintech product needed a clear, mobile-ready dashboard that stayed fast under real API load - not a slide-deck mock.

My role as Web-App Developer

End-to-end web build: UI architecture, REST integration, responsive polish, and pre-launch performance QA.

Process & tools

  1. I

    Scope & IA

    Mapped dashboard flows, auth edges, and mobile breakpoints before pixels.

  2. II

    UI Build

    Shipped componentized React views with a performance-first Tailwind layout.

  3. III

    API Wire-up

    Integrated REST endpoints for balances, transfers, and live chart data.

  4. IV

    Polish & Ship

    Lighthouse pass, cross-browser QA, then production deploy.
