PROFILE
Oleksandr Liakhevych
Oleksandr Liakh enhanced data handling and reliability in the aws/aws-sdk-net and open-telemetry/opentelemetry-dotnet-contrib repositories over a three-month period. He delivered comprehensive unit tests for DynamoDBEntryConversion, expanding coverage for primitives, collections, and edge cases using C# and the AWS SDK. In open-telemetry/opentelemetry-dotnet-contrib, he improved AWS Lambda instrumentation by hardening error handling for empty LambdaContext scenarios and ensuring robust functionArn processing. Oleksandr also added DateOnly and TimeOnly support to DynamoDBContext for .NET 8.0+, implementing converters and tests to ensure correct serialization and backward compatibility. His work demonstrated depth in .NET development, data serialization, and instrumentation.

1 Commits • 1 Features
Mar 1, 20252025-03 Monthly Summary – Focused on expanding .NET 8.0+ compatibility and data-model ergonomics in the AWS SDK for .NET. Delivered DateOnly and TimeOnly support in DynamoDBContext, including converters and tests, enabling correct serialization/deserialization and backward compatibility (DateOnly reads back as DateTime). This work improves developer experience for customers targeting modern .NET versions and reduces manual data handling for DateOnly/TimeOnly data in DynamoDB.
