About this gig

Is your ASP.NET Core API throwing 500 errors, timing out, or returning wrong data? I'll find the root cause and fix it.

I'm a Development Lead with 23 years in software, working across healthcare and payments. I've upgraded apps to .NET 6/7, worked with Azure, Redis, Okta, Identity Server, Docker and Kubernetes, and tuned large Oracle and SQL Server databases.

What I fix:

- Errors and exceptions in controllers, middleware and DI

- Authentication issues (JWT, Okta, Identity Server)

- Slow or wrong Entity Framework Core and Dapper queries

- SQL Server and Oracle errors, deadlocks and timeouts

- Serialization, routing, CORS and configuration problems

- .NET version upgrade breakages

What you get:

- Fixed, tested code with clear comments

- Explanation of the root cause

- Tips to prevent the issue from coming back

I work in your repo or a zip of your code. Production access is not needed. Message me with the error and a short description before ordering, and I'll confirm the right package.

Users are impatient: most won't wait more than 8 seconds for a page to load. I make slow systems fast. 23 years as a .NET and database developer and architect in healthcare, banking and payments. I've tuned a 2 TB Oracle database for complex searches, redesigned SQL Server schemas for high-volume apps, and built ASP.NET Web APIs on Azure and AWS. You get before/after timings, safe scripts with rollbacks, and plain-English explanations. Send me your slow query for a free quick review.
