Worked on the Cysharp/NativeCompressions repository to enhance compression performance and build reliability. Delivered two features, including improvements to Zstandard integration by updating native binaries, aligning build flags with upstream, and introducing benchmarks to support data-driven performance decisions. Improved LZ4 compression and decompression throughput on .NET 8 and above by replacing Task.WhenAll with Parallel.ForAsync, leveraging parallel processing for better efficiency. Maintained repository alignment with upstream changes and focused on performance optimization through benchmarking. Utilized C#, .NET, and YAML to implement asynchronous programming patterns, optimize build systems, and support continuous integration workflows, demonstrating depth in both compression algorithms and CI/CD practices.
