Shipped a crypto portfolio tracker focusing on frontend fundamentals and real-time data handling.

Key features: • Real-time portfolio tracking with WebSocket price feeds • Interactive charts and P&L calculations
• Solana wallet integration (Phantom/Solflare) • Automatic token balance detection • Responsive design across devices

Tech stack: React + TypeScript, Solana Web3.js, Recharts, Tailwind CSS, CoinGecko/Jupiter APIs

Key insight: Most web3 apps are traditional web apps with targeted blockchain integration. Built 90% of functionality frontend-first, with smart contract integration planned for user preferences storage.

Currently working on the Solana program component for persistent user data.
