About
The Performance Engineering skill provides a robust framework for validating system capacity and resolving resource bottlenecks across the entire application stack. It equips developers with standardized patterns for load, stress, and soak testing using tools like k6 and Locust, alongside deep profiling techniques for CPU, memory, and I/O. By integrating performance SLOs, database query optimization, and Core Web Vitals improvements, this skill ensures applications remain fast, reliable, and cost-effective under varying traffic volumes.
