We're experts in .NET Framework and relational database programming. Our involvement may help to handle the following categories of issues:

  • Database programming:
    • Frequent deadlocking or version conflicts
    • Query performance – index and query optimization
    • Scalability
    • Architecture (transaction boundaries, correct isolation, standard compliance, etc.)
  • .NET programming:
    • Application performance and scalability (check out tips.x-tensive.com)
    • Architecture (compatibility with .NET Framework and industry standards and patterns, etc.)

And obviously, we perfectly handle any issues related to use of our own products.

What can we do?

We can:

  • Analyze your project and identify the places (particular code) leading to the specific issue(s)
  • Explain why the issue occurs
  • Provide an advice allowing to fix it
  • Show it will really resolve the issue
  • Finally, we can fix the issue by our own.
