Developed enhancements for Spanner read operations in the googleapis/google-cloud-dotnet repository, focusing on adding support for orderBy and lockHint options to improve query flexibility and determinism. Leveraged C# and .NET to implement these features, ensuring robust integration with the existing Spanner client library. Employed test-driven development practices by creating comprehensive tests that validate the new options and protect against regressions. The work emphasized maintaining compatibility with current clients and continuous integration pipelines, resulting in stable and reliable feature delivery. Demonstrated skills in API development, backend engineering, and cloud database technologies while addressing customer needs for greater control over read semantics.
