Engineering Notes

Short write-ups, lessons learned, and performance tips direct from the dev desk.

Lesson Learned

Avoid dynamic classnames with Tailwind

Always write full Tailwind classes. Avoid mapping like dynamic string templates (e.g. bg-[color]-500). Tailwind static analyzer won't bundle them.

Next.js Tip

Disable Next.js prefetching on big nav menus

Using `prefetch=` on non-critical links inside footer/menus prevents excess bundle pre-loading, lowering LCP values.

Performance Tip

Target CLS via Stable aspect-ratio

Set `aspect-ratio` on wrapping containers of dynamic elements. This ensures container reserves space before the bundle loads.

AI & Workflow

How we utilize AI models to design, develop and ship premium systems.
