I’m building a CRM from scratch with C# / ASP.NET Core MVC (.NET 10) and MS SQL Server and need a developer who can pair robust architecture with a polished, enterprise-grade UI. Features are attached with this post. Role-based access control Admin, Salesexecutive, and Customer Support Agent profiles should be available out of the box, each with easily adjustable permissions from an Admin panel. Tech stack & code quality - C# / ASP.NET Core MVC (.NET 10) with a clean, layered solution (Domain, Application, Infrastructure, Web). - EF Core (code-first), DI, async best practices. - MSSQL back-end. - Responsive, modern UI (Razor pages or Blazor are both fine) that feels consistent with enterprise SaaS products. - Source control in Git with tidy commits and a readable README that explains local setup and deployment. Acceptance criteria 1. All listed features run end-to-end on a fresh MSSQL database. 2. Responsive UI clears Lighthouse and cross-browser checks. 3. Each role’s permissions verified with test accounts. 4. Email-marketing and social-media integrations authenticate and exchange data. 5. Clean code, commented where needed, delivered via a Git repo with build instructions. If you can leverage any existing modules to speed things along, just note it in your proposal. Otherwise, I’m expecting original, well-documented work and a clear path to the first deployable version.

Hello, I’ve reviewed your requirements for building a CRM using ASP.NET Core MVC (.NET 10) and MS SQL Server, and I’m confident I can deliver a clean, scalable, enterprise-grade solution. I work with C#, ASP.NET Core, EF Core (code-first), and MSSQL, following a layered architecture (Domain, Application, Infrastructure, Web) with async best practices, DI, and secure RBAC. I can implement Admin, Sales Executive, and Support Agent roles with configurable permissions via an admin panel. On the UI side, I can build a responsive, modern SaaS-style interface using Razor Pages or Blazor, optimized for cross-browser compatibility and Lighthouse checks. I’m comfortable integrating email marketing and social media APIs, handling authentication, and ensuring reliable data exchange. All work will be delivered via Git with clean commits, a clear README, setup instructions, and deployment guidance. If existing modules help speed delivery, I’ll document them clearly; otherwise, you’ll receive original, well-structured, maintainable code with a clear path to first deployment. Happy to discuss feature scope, timeline, and UI preferences. Best regards, Shakti Singh Tanwar
