A WooCommerce recommendation engine kept timing out the server, and the weights oscillated instead of settling. Swapping the basic update rule for Momentum and then Adam is what fixed it, and this explains why adaptive step sizes matter on messy data.
A hero illustration that looked right at 16:9 and collapsed on mobile. Instead of shipping two SVG files, I moved the artwork into a hidden symbol library and referenced it from two wrappers with different viewBox values, then animated the use elements.
I inherited a landing page with 450 lines of IDs, duplicate selectors and !important flags everywhere. Notes on moving it onto cascade layers: the five-layer order I settled on, where media queries belong, and why !important inverts layer priority.
A client handed me an MVP he had built over a weekend in Cursor. It looked polished until I tried to add one calculation and found no schema underneath any of it. This is the case for settling the data model before you open a coding assistant.
I spent three hours hand-coding cubic-bezier keyframes for a WooCommerce build and the bounce still felt stiff. A spring-based SVG animation workflow with SMIL exports got it right and kept the animation inside the asset.
A client was shipping a 4MB transparent PNG for every header to get a 1950s cartoon look, which killed load time and left the page with no real headings. Layered text-shadows, paint-order and a small jiggle animation do the same job in CSS.
A client’s desktop PageSpeed score was 98 while his conversions fell. Why lab tests miss what real visitors feel, and how to time a WooCommerce cart action with the User Timing API.
A WooCommerce boutique was choking on JS sliders and a custom select. Swapping them for native CSS selects, scroll-marker carousels and scroll-state queries cut a second off Time to Interactive.
A client’s wallpaper gallery took down its own dashboard hours after launch. Pruning the image sizes WordPress generates and offloading originals to object storage cut upload processing by about 70%.
An agency gallery held 14 years of high-resolution assets and took 12 seconds to load. Caching the resolution URLs in a transient made it worse; generating the links from a CDN naming convention fixed it.
