You will get SQL Server and EF Core performance optimization for your .NET application
Project details
Improve slow SQL Server and Entity Framework Core operations in your .NET application through focused, evidence-based performance optimization.
I will review the affected SQL queries, EF Core LINQ expressions, execution plans, indexes, tracking behavior, loading strategies, database calls, blocking, timeouts, and resource usage to identify the actual bottlenecks.
Depending on the selected package, the work may include query rewriting, index recommendations, projection improvements, AsNoTracking usage, N+1 query reduction, pagination review, deadlock or timeout analysis, and API or repository-level corrections.
You will receive the optimized SQL or source-code changes, a clear summary of the findings, before-and-after validation results where measurable, implementation notes, and practical recommendations for maintainable production use.
This service is suitable for ASP.NET Core APIs, web applications, background services, and other .NET systems using SQL Server and EF Core.

About Guney Can
Senior Software Engineer C#/.NET | ASP.NET Core APIs & Payment Systems
Istanbul, Turkey - 4:56 am local time
I’m a senior C#/.NET developer with 17+ years of professional software development experience. My main focus is ASP.NET Core, REST APIs, SaaS platforms, payment systems, e-commerce infrastructure, SQL Server, and enterprise web applications.
I can help you with:
• Building secure ASP.NET Core APIs and backend systems
• Fixing bugs and completing unfinished .NET projects
• Integrating payment gateways, 3D Secure, webhooks, and external APIs
• Developing SaaS, e-commerce, ERP, and business applications
• Improving SQL Server queries, API performance, and application architecture
• Modernizing legacy ASP.NET and .NET applications
• Deploying applications to IIS, Windows Server, Azure, or Plesk
• Integrating OpenAI and AI-powered document processing features
• Reviewing existing code and creating a practical improvement plan
My core stack includes C#, .NET, ASP.NET Core, Entity Framework Core, SQL Server, REST APIs, JavaScript, HTML, CSS, Git, Docker, IIS, and Azure.
I’m comfortable taking ownership of the full development process—from understanding the business requirement and designing the architecture to implementation, testing, deployment, and production troubleshooting.
You will receive clear communication, maintainable code, realistic estimates, and a solution designed around your actual business needs.

Performance Review and Baseline
I review the reported issue, relevant code, SQL or EF Core operation, technical environment, and available metrics to establish the current performance baseline.
Query and Execution Plan Analysis
I analyze the affected queries, execution plans, scans, joins, filters, blocking behavior, database calls, and resource usage to identify the root causes.
