.NET/C# Developer — SaaS Refactor of Existing ASP.NET Core App

We're converting an existing ASP.NET Core MVC app (.NET 8, EF Core, SQL Server) — currently a single-user app with some e-commerce functionality — into a multi-tenant SaaS platform for a niche creative/professional audience. Looking for a developer who can: Get up to speed on the existing codebase quickly and give a clear-eyed take on what's solid vs. what needs rework Help us convert it to proper multi-tenant architecture with data isolation Modernize auth (currently basic, needs hardening) Work alongside our small team on ongoing feature development from there This starts with a short paid review/scoping period so we can agree on realistic timeline and cost before committing to the full build. What we need: Solid .NET / ASP.NET Core / EF Core background, ideally with SaaS or multi-tenant experience Someone who communicates clearly and flags risks early rather than just plowing ahead Comfortable working with a small, fast-moving team NDA required before repo access. Send a short note on relevant past projects (multi-tenant conversions especially) rather than a generic cover letter.
