An NFT marketplace with wallet-based sign-in and portfolio views. The interface connects wallet state, authenticated sessions and asset information within a distinctive visual design.
My role
Developer within the product team, contributing to frontend and backend features. My main areas were wallet authentication, session flows and the portfolio interface.
What I delivered
- Implemented wallet connection, login and logout flows with session-aware interface states.
- Built a portfolio dashboard displaying NFT assets and user connections.
- Handled wallet-provider differences, connection errors and fallback states.
- Delivered responsive interfaces and resolved layout and interaction details where designs were incomplete.
The challenge
Keep wallet connection, authentication and application state aligned while handling provider differences and interrupted user flows.
