About this gig

Is your existing C Sharp or ASP NET Core application failing, returning errors, or behaving incorrectly? I will reproduce the issue, trace the cause, and deliver a focused code fix within the agreed scope.


This Gig is for existing NET codebases. It can cover backend logic, REST API behavior, exceptions, dependency or configuration issues, database interactions, and related tests where feasible. You receive the changed code plus a concise explanation of the cause and fix.


Please contact me before ordering if the issue cannot be reproduced reliably, the repository is very large, or production access is required. New features, redesigns, large migrations, security audits, and unrelated bugs are outside the package and can be scoped separately.
