Worked on the crossoverJie/starrocks repository, delivering targeted improvements in backend development and build systems. Developed a feature to enhance query optimization statistics for LIKE and ILIKE expressions, ensuring statistical outputs are consistent and accurate for better SQL optimization. This involved refining the ExpressionStatisticsCalculator and adding comprehensive tests to validate the changes. Additionally, addressed build system compatibility by updating shell scripts to use a generic build system variable, improving reliability across diverse environments. Leveraged Java and shell scripting skills, with a focus on database performance tuning and robust build processes. The work demonstrated depth in both statistics engineering and build modernization.
