Hyvä vs Luma benchmark – real numbers, LCP 3.5x faster, k6 load test, conversion
Hyvä is faster than Luma – everyone says so. But by how much, on what metrics, and does it translate to business results? I ran controlled benchmarks on identical hardware with the same Magento 2.4.8 installation and both themes, measuring LCP, TTFB, Lighthouse scores, and load test results with k6. The numbers are concrete.

Kubernetes for the PHP developer – kubectl debugging, Deployment YAML, HPA, troubleshooting
Most PHP applications eventually run on Kubernetes – but developers rarely touch it until something breaks in production. Understanding the basics of Deployments, Services, ConfigMaps, and HPA makes debugging much faster. I show the minimum Kubernetes knowledge a PHP/Magento developer needs: reading logs, exec into pods, understanding why a pod is crashing, and writing a sensible Deployment YAML.
