Worked on backend development in C# to enhance the reliability of hash-based collections within the ThioJoe/_TempFork_PowerShell repository. Focused on correcting the GetHashCode method for array members in the PSMethodInvocationConstraints class, addressing a core issue that previously risked runtime errors in dictionaries and HashSet usage. The solution involved careful debugging and refactoring to ensure accurate hash code generation, directly improving code correctness and maintainability. This work demonstrated strong attention to code quality and issue tracking, aligning changes with repository standards and documented issues. The approach emphasized disciplined problem-solving and a commitment to robust backend engineering practices in C#.
