FAQ
Can you fix urgent production bugs in my C# ASP.NET web application?
Yes, absolutely! I specialize in advanced debugging and live production support. If your live ASP.NET Core Web API is crashing, showing database connectivity errors, or throwing exceptions, I can debug and fix the bug quickly.
Do you follow clean architecture and repository patterns?
Yes, coming from a Systems Analyst background, I write enterprise-grade, clean, and maintainable code. I implement robust security, dependency injection, and repository patterns using Entity Framework or raw SQL queries.
Can you handle complex database queries and optimize performance?
Yes, database management is one of my core strengths. Alongside C# backend development, I specialize in writing complex SQL Server and MySQL queries, performance tuning, and creating optimized databases for commercial-scale apps.
What do you need from me to start fixing the bug or building the API?
I will need a clear description of the issue or your API requirements, access to your C# .NET project source code, and your database schema details
