.NET Developer for Crypto Pre-Trade Risk Checker

@kamran2012

Good to see this project, I will wire PostgreSQL with EF Core migrations, implement JWT auth with per-user data isolation, and harden the risk engine — then move through webhook security, Telegram alerts, and CI/CD across your three required phases. For the PostgreSQL + JWT approach, I will replace AppStore with EF Core DbContext using owned entity mappings, add a JWT bearer scheme with refresh tokens, and scope every query through a user ID filter — so tenant isolation is enforced at the repository level rather than relying on controller logic alone. Questions: 1) For the token safety API in Phase 2, do you have a preferred provider — GoPlus, RugCheck, or another — or should I evaluate options? 2) Are you targeting Azure App Service or a self-managed VPS for production deployment? Send me a message and we can go over the details. Best regards, Kamran

Hi, how are you doing? I have solid C# and ASP.NET Core 8 experience, with hands-on work on Blazor WASM and PostgreSQL + EF Core in SaaS and fintech dashboards. I’ve built production-ready risk, rules, and webhook flows, plus secure auth and per-user data isolation. I can deliver Phase 1–3 with clear docs, tests, and CI basics, plus a simple deployment path. I’ll share two similar projects and a concise phase plan with screenshots of current work. Let me know further if interested

@emanz03

What I like about this project is that it is intentionally designed as a risk-control system rather than another “AI trading bot.” The current architecture already separates the important domains properly RiskEngine, Rules, Token Scan, Webhook ingestion, Alerts, and Journal workflows so I would focus on productionizing the existing structure instead of rewriting it. For Phases 1–3, my approach would be: • replace AppStore with PostgreSQL + EF Core repositories • implement JWT auth + strict per-user data isolation • harden TradingView webhooks with user-scoped keys + validation • isolate RiskEngine into fully testable service logic • integrate real token-risk providers through adapter-based services • add CI/testing/deployment flow before feature expansion The Technical Guide is actually well thought out and gives a strong roadmap already, especially around webhook normalization, decision scoring, and journal/risk workflows. For deployment, I would likely recommend Dockerized API + PostgreSQL + Blazor hosting with GitHub Actions CI so local/dev/prod environments stay consistent. Before finalizing architecture decisions, the main thing I’d want to clarify is whether this is expected to remain a relatively small trader-focused MVP initially, or if you already plan to evolve it into a larger multi-user SaaS platform shortly after stabilization.

@techsty2014

Hey, We will wire TradeCheck to PostgreSQL with EF Core migrations, add JWT auth with per-user data isolation, and harden the risk engine across all four phases. For the database swap, we will register a DbContext per entity group, seed initial trading rules via migrations, and store each user's journal and alerts behind a tenant filter. JWT refresh tokens will sit in an HttpOnly cookie so the Blazor WASM client stays stateless. A couple of quick things to confirm: 1) Is the current in-memory AppStore a single static class, or are there multiple service interfaces we need to map to EF repositories? 2) For the token scanner in Phase 2, do you have a preferred API (GoPlus, RugCheck), or should we evaluate and recommend one? The number quoted here is a starting estimate. Send me a message and we can go over the details. Best regards, Faizan

@albertc1996

Hi there, migrating your in-memory Blazor and ASP.NET Core MVP to PostgreSQL often introduces severe concurrency issues if DbContext isn't properly scoped for async TradingView webhook bursts. Amateurs miss this completely. And it causes silent data corruption. I will Ensure your JWT implementation securely isolates per-user payload validation. I'll Deliver a robust production architecture ready for real-time crypto parsing. I recently replaced an in-memory API with a high-performance EF Core and PostgreSQL stack for a proprietary trading dashboard, reducing API latency to under 40ms during high-volume webhook bursts. I include a free GitHub Actions CI/CD pipeline setup. Are you planning to validate the TradingView payloads using HMAC signatures, or strictly IP whitelisting with a per-user secret token? Let's discuss.

@Dliteinformation

I am very excited about the chance to contribute my expertise to your Crypto Pre-Trade Risk Checker project! With over 3 years of hands-on experience in C# and ASP.NET Core, combined with a deep understanding of Blazor and PostgreSQL + EF Core, I'm confident that I will effectively smoothen your MVP into a production-ready software. My past accomplishments align closely with the deliverables you seek, as I've successfully developed SaaS and dashboard projects, ensuring their robustness and scalability. Regarding PostgreSQL + JWT for this codebase, I propose leveraging JWT bearer authentication in ASP.NET Core for your user authentication and data isolation requirements. This will provide a secure way to manage authentication tokens and control access across different endpoints and user levels. It nicely complements our choice of a PostgreSQL database, ensuring efficient database interaction through Entity Framework Core. When it comes to scheduling codecalls, I'm based in [X], giving us the advantage of overlapping time zones for smooth collaboration. My workweek includes flexible options, providing ample availability for weekly progress updates at your convenience. Lastly, if flexibility is essential, I'm open either to fixed-price or hourly terms for Phases 1-3; whatever arrangement serves you best! Don't wait any longer—hire me now so we can turn your demo into a robust production-ready application together!
