Fix the issue, understand its cause and make your existing .NET application easier to maintain. I bring 3+ years of professional C#/.NET experience, including production debugging, API integration and WPF/web application work.

Scope • ASP.NET Core API bugs, validation errors and integration failures • Authentication/authorization defects and role-based access behavior • Background-job failures, retries and application diagnostics • WPF/MVVM workflow fixes and agreed desktop enhancements • Existing .NET features and performance problems within an agreed scope

Deliverables • Reproduction steps and a concise root-cause explanation • Reviewed code changes in your repository • Regression tests or documented verification appropriate to the issue • Deployment/setup notes and a clear handover

Process and pricing Share the stack, symptoms, sanitized error details and expected behavior. I review the issue, agree on a focused milestone and estimated hours, implement the fix and verify it with you. $25/hour; scope, access and timeline are agreed before work begins. The displayed duration is indicative and does not promise resolution of every issue within one week.

Relevant experience Professional .NET API and WPF/web integration work on ABIS, plus independently launched SachAI with resilient background processing, authentication and operational diagnostics. Confidential employer materials stay private.
