.NET Developer for Crypto Pre-Trade Risk Checker
Summary
Freelancer Client is hiring: .NET Developer for Crypto Pre-Trade Risk Checker.
Location: Remote
Compensation: 500$~750$
.NET Developer — Finish Crypto Trade Risk Checker MVP (Blazor + ASP.NET Core 8)
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. ASP.NET Core 8 (minimal API)
What you'll do:
• PostgreSQL + Entity Framework Core; replace in-memory AppStore
• User authentication and per-user data isolation
• Enforce all trading rule fields in the risk engine
• API/client configuration for dev and production URLs
• Integrate a real token safety API (replace mock scanner)
• Secure TradingView webhooks (per-user keys, validation)
• Telegram (or similar) notifications for high-risk / blocked trades
• Unit tests for risk logic; basic API tests
Requirements:
• 3+ years C# / ASP.NET Core
• Blazor WASM experience
• PostgreSQL + EF Core
• REST API design and webhook security
• Comfortable auditing and documenting Windows desktop deployment behavior
• Clear English communication; weekly progress updates
Nice to have:
• Read-only exchange API sync (positions / daily PnL)
• Multi-tenant / subscription hooks
• Crypto/trading domain knowledge
• Experience with TradingView alerts
• Telegram Bot API
Skills: Linux, C# Programming, Azure, PostgreSQL, ASP.NET, Docker, Trading, .NET Core, Blazor, REST API
