Derek Herman

During February 2025, Derek Herman enhanced the woocommerce/woocommerce-square repository by implementing comprehensive performance instrumentation for the Square payment gateway. He developed PHP backend logging to capture transaction timing and memory usage, gated by debug mode for targeted error reporting, and introduced JavaScript-based frontend logging to monitor classic checkout steps with server-side metric reporting. To aid debugging and bottleneck analysis, Derek created Mermaid diagrams visualizing logging points across the stack. He also improved code quality by addressing PHP CodeSniffer issues and refining formatting for better readability. This work deepened observability and maintainability, leveraging PHP, JavaScript, and diagramming skills throughout.
