Developed and optimized a Dockerized DuckDB-PostgreSQL benchmark suite for the ClickHouse/ClickBench repository, enabling repeatable end-to-end performance testing with robust environment setup, data loading, and query scripting. Improved reliability by reducing query failures and mounting Parquet data directly from storage to enhance load times and consistency. In the ClickHouse Go client repositories, implemented performance optimizations for string-to-byte conversion using Go’s unsafe features, eliminating unnecessary dependencies and reducing processing overhead. Standardized atomic operations by migrating to Go’s sync/atomic, streamlining dependency management and improving maintainability. Work focused on Go, SQL, and Docker, emphasizing performance, reliability, and codebase consistency across projects.
