I will optimize your slow entity framework core and sql queries


About this gig
Is your .NET application slow? Do pages take seconds to load, or does your database CPU spike under load?
I'm a backend .NET developer specializing in Entity Framework Core and SQL performance. I find *why* your queries are slow and fix them without breaking your existing logic.
*What I can do for you:*
- Diagnose slow EF Core queries (N+1 problems, over-fetching, bad tracking, cartesian explosions)
- Rewrite LINQ and raw SQL for speed
- Add and tune database indexes
- Fix slow list/grid pages and large data-table loads
- Explain what was wrong and how I fixed it, in plain language
*Works with:* ASP.NET Core, EF Core, SQL Server, PostgreSQL, Dynamic LINQ
Send me your slow query, endpoint, or a description of the problem and I'll tell you exactly what can be improved before you order.
*FAQ:*
- *Do you need access to my database?* I can work from your query + schema, or a sample/anonymized database. No production credentials required.
- *Can you guarantee it will be faster?* I guarantee a diagnosis and concrete improvements. Real-world gains depend on your data and setup; I'm honest about what's achievable before you order.
- *Which databases?* SQL Server and PostgreSQL.
