PROFILE

Blair Huang

Worked across multiple AWS observability repositories, focusing on enhancing cross-account tracing and improving telemetry data quality. Delivered features in aws-otel-python-instrumentation and aws-otel-js-instrumentation to extract and enrich span attributes, supporting services like DynamoDB, Kinesis, and S3. Applied targeted refactoring and code cleanup in Python and JavaScript to improve maintainability and future-proof ARN parsing and account ID validation. In awslabs/mcp, addressed metric misclassification by mapping fault metrics to availability, adding regression tests to ensure accuracy. Leveraged skills in Python, Java, and TypeScript, with a strong emphasis on distributed tracing, OpenTelemetry instrumentation, and robust automated testing practices.
