April 2025 monthly summary: Focused on performance benchmarking for the scylladb-javascript-driver repository. Implemented a new Concurrent Select Benchmark across JavaScript and Rust, and enhanced benchmarking visualizations by switching time and memory plots to a logarithmic scale for better differentiation under higher load. Included a fix to the benchmark axis scaling (x-axis) to improve readability at high volumes. These efforts delivered richer, more actionable performance insights, enabling data-driven optimizations and stronger cross-language comparisons. Demonstrated competencies in benchmarking, cross-language integration, and data visualization.
