I need a secure, web-based panel that lets users liquidate their crypto directly into Indian Rupees. The flow is straightforward: a visitor creates an account with an email-and-password signup, checks the live conversion rate for the supported coins, chooses the amount to sell, confirms, and then reviews the completed order in a personal transaction log. Core requirements • Web interface only—no mobile client at this stage. • Real-time price feed so every quote shown and every sell order reflects the current market. • Simple user account area where people can update profile details and see an at-a-glance balance. • Transaction history page that records date, coin, INR value, status and reference ID. Technical notes You are free to pick the back-end stack (Node/Express, Django, Laravel, etc.) as long as it supports REST or GraphQL endpoints that I can consume later from other services. For pricing data, any reliable public API such as CoinGecko, Binance or Kraken is fine—just cache responses sensibly. All sensitive actions must travel over HTTPS and passwords stored with salted hashing. A responsive front end is required so the panel renders cleanly on desktop and mobile browsers alike. Deliverables 1. Source code in a public or private Git repository 2. A one-click deployment guide (Docker compose or similar is ideal) 3. Brief README covering environment variables, API keys and how to add more coins Acceptance criteria • I can spin up the project locally in under ten minutes. • A newly created user can log in, fetch live rates, sell a coin and immediately see the entry in their transaction history. • All inputs are validated and no critical warnings appear in console or server logs during normal use. Once these checkpoints pass, I will sign off the milestone and proceed with the next phase, which will be bank settlement integration.
