.NET E-commerce Catalog Integration

I’m creating an e-commerce solution and I need an experienced .NET developer to build the core product-catalog and search module. The goal is to deliver a fast, searchable catalog that plugs smoothly into our existing inventory management and customer management systems, all written in clean, maintainable C#.

Here’s what I need from you:
• A relational schema (SQL Server preferred) that supports categories, variants, stock levels, and rich product metadata.
• RESTful or gRPC endpoints in ASP.NET Core for catalog CRUD and advanced search (keyword, filters, pagination, sort).
• Real-time sync routines or webhooks that keep the catalog in step with our inventory management platform and update customer profiles with browsing data.
• Solid test coverage plus concise setup documentation so the in-house team can extend the codebase.

Nice-to-haves—only if you’ve done them before—include ElasticSearch or Azure Cognitive Search for lightning-fast queries, and Swagger/OpenAPI docs to speed up front-end integration.

Please share a brief outline of your proposed architecture, any relevant GitHub or live links, and the estimated timeline to reach a production-ready release. I’m ready to start as soon as I find the right fit.
