Sudheer focused on improving test reliability in the sonic-net/sonic-mgmt repository by addressing flakiness in MTU-related test cases. He developed a targeted fix in Python that ensures MTU changes propagate fully through the hardware path, from configuration databases to the SAI layer, and introduced a method to count ports with updated MTU values for accurate end-to-end verification. By optimizing verification timing and increasing wait periods for hardware updates, Sudheer reduced false negatives and stabilized continuous integration runs. His work demonstrated depth in networking and testing, delivering a robust solution that enhances the determinism and efficiency of MTU validation workflows.
