I need a clean, lightweight crypto-to-crypto and crypto-to-fiat converter that I can brand as “Alex.” The core idea is simple: a user enters an amount, selects two currencies, and immediately sees the converted value pulled from a reliable, up-to-the-second price feed such as CoinGecko, CoinMarketCap, or a comparable public API. I’m flexible on stack and format—web, desktop, or mobile all work—as long as the interface stays intuitive and responsive. Future growth matters, so an easy way to plug in extra coins or new fiat pairs without rewriting large chunks of code is essential. Clear internal comments and a short README that explains setup, API keys, and update routines will round out the hand-off. Deliverables: • Fully functional converter branded “Alex” • Source code with clear comments • README covering build/run steps, API access, and how to add new currencies If you’ve tackled similar financial or blockchain tools before, let me know—efficiency and accuracy are top priorities here.
