Contributed to the apache/datasketches-go repository by implementing core data sketch algorithms in Go, focusing on ReservoirItemsSketch and VarOptItemsSketch with robust serialization and cross-language compatibility with Java. Enhanced the codebase through targeted refactoring, aligning logic with Java’s twoWayMergeInternal and improving maintainability. Developed comprehensive unit tests, including integration of Java-generated test data to ensure serialization consistency across languages. Addressed a critical bug in ReservoirItems Family ID handling and optimized performance through code improvements. Leveraged skills in Go, Java, and data serialization to deliver features that support scalable backend development and facilitate reliable, high-performance data processing in distributed systems.
