.NET 8 Developer for Crypto TradeCheck MVP

.NET Developer — Finish Crypto Trade Risk Checker MVP (Blazor + ASP.NET Core 8)

Duration: 4–6 weeks (phased)
Budget: 500$~750$

About the project
TradeCheck is a pre-trade risk checker for crypto traders. It is not a trading bot. Users enter a trade setup and get a risk score, suggested position size, max loss, and a decision: Safe, Reduce Size, or Do Not Trade. The MVP also includes trading rules, a mock token scanner, TradingView webhook alerts, and a trade journal.

The core app is built. I need an experienced .NET 8 developer to take it from demo/MVP to production-ready.
