PhuongLinh Nguyen developed a configurable split-mode parsing feature for list-of-pairs in the ARM-software/golang-utils repository, enabling users to choose between splitting at the first occurrence or all occurrences of a separator. She introduced a new PairSplitMode type and adopted the Functional Options pattern to enhance parsing configuration and API usability. Her work included modernizing the codebase, updating both implementation and unit tests in Go, and stabilizing continuous integration by addressing lint issues. This feature improved data parsing workflows, allowing downstream consumers to adjust splitting behavior efficiently, and demonstrated a solid grasp of Go, software development, and unit testing practices.
