PROFILE

Xl Liang

Worked on backend development and documentation across open-source projects, focusing on targeted improvements. In the tarantool/datafusion repository, addressed a bug by ensuring percent-encoding was preserved in PartitionedFile paths during deserialization, using Rust and the Path::parse method to maintain data integrity and prevent routing errors. Added unit tests to validate the fix and guard against regressions. Later, contributed to apache/iceberg by enhancing project documentation, specifically adding and aligning Sail’s entry in the vendors list and navigation. Used Markdown and technical writing skills to improve discoverability and onboarding, ensuring consistency with existing integration and vendor documentation standards.
