I need a straightforward cryptocurrency converter that lets a user enter an amount, choose two coins, and instantly see the converted value. Nothing fancy—just a clean interface backed by live price data from a reliable API such as CoinGecko, CoinMarketCap, or a service you recommend. Stack and platform are open; a lightweight web page in vanilla JavaScript works, but React, Vue, Flutter, or an Electron shell are also fine. Start with a small list of popular coins and structure the code so I can add or remove tokens later without touching the core logic. Deliverables • Complete, well-commented source code • README with setup, run, and deployment instructions • Short screencast or screenshots showing the converter in action Acceptance criteria Entering an amount, selecting any supported pair, and receiving an accurate result that matches the API at that moment—all within roughly two seconds. Let me know which tech stack you prefer and how quickly you can have a working prototype ready.

Hi I can build a clean, fast cryptocurrency converter that delivers accurate, real-time pricing using a reliable API like CoinGecko or CoinMarketCap. The main technical challenge is ensuring conversions update instantly while remaining easy to extend with new tokens, and I solve this by separating API logic from the UI so coin lists can be updated without touching core code. I can implement this as a lightweight web page in vanilla JavaScript or a small React/Vue app if you prefer a component structure. Users will simply enter an amount, pick two coins, and get a live conversion within about two seconds. The interface will stay minimal, clear, and optimized for quick lookups. You’ll receive well-commented source code, a full README, and screenshots or a screencast of the tool running. The final result will be a smooth, accurate, and easy-to-maintain converter. Thanks, Hercules
