Developed and delivered a PJRT Protobuf Profiling Data to JSON conversion feature for the zml/zml repository, enabling streamlined analysis and visualization of profiling outputs. The work involved implementing an end-to-end data transformation pipeline using Zig and Bazel, introducing new build rules and source files to automate the conversion process. By integrating JSON serialization and protocol buffer handling, the feature reduced manual data wrangling and accelerated performance debugging for PJRT workloads. This addition improved developer productivity by providing clearer visibility into runtime behavior, supporting data-driven optimization, and enhancing the profiling data pipeline without introducing new bugs during the development period.
