Healthcare recruiting search combined strict filters with marketing expectations for speed. Pure client-side rendering would not cut it for hundreds of listings; ISR let us prebuild high-traffic combinations and revalidate on a sane cadence.
Hybrid rendering meant the shell and critical listing content arrived quickly, while heavier profile modules could defer. The design system mixed Tailwind utilities with MUI components where complex inputs already existed–consistency via tokens, not dogma.
Accessible sliders and advanced search drawers had to work with keyboard and screen readers because the domain is regulated and user trust matters. We treated a11y as a requirement alongside performance.
The metric that mattered was discovery latency under load: ISR plus disciplined caching of filter facets kept the job search experience sub-second for the paths recruiters used daily.
