Fix Mobile Responsiveness, Layout & Pagespeed Issues on WordPress (Divi) Website

We're a small industrial services company with an established WordPress site built on the Divi theme/builder, hosted on Cloudways. The desktop layout is solid but several pages have visible GUI/layout problems on mobile such as things like overlapping or misaligned elements, oversized images/text, awkward spacing, and modules stacking in the wrong order. We need an experienced Divi developer to audit the site on mobile and fix these issues page by page. As a bonus, our ideal hire would have direct experience in improving mobile pagespeed for sites similar to ours. Desktop pagespeed for our site is generally strong, we do not wish for any changes made on mobile to affect this. Site Environment - CMS/Builder: WordPress + Divi - Hosting: Cloudways - CDN/Caching: Cloudflare & Varnish - Current status: Desktop pages are finalized and should NOT be altered. Most desktop pages currently score well on Core Web Vitals / page speed and are suitable from an aesthetics standpoint — any mobile fixes must not regress load times or performance scores. Scope of Work 1. Full mobile audit — Review every page of our site on mobile (~375–430px) breakpoints and document all layout/visual issues found (a short list or annotated screenshots is fine, no need to spend time breaking this down for us). 2. Fix responsive settings in Divi — Correct per-breakpoint sizing, spacing, padding/margins, image scaling, text sizing, and element show/hide settings so pages look clean and intentional on mobile. Not just "not broken." 3. Custom CSS where needed — For edge cases Divi's built-in responsive controls can't handle cleanly, targeted custom CSS/media queries are acceptable. 4. Cross-device/browser testing — Test on real mobile browsers (Firefox, Android Chrome), not just a resized desktop browser window. 5. No desktop regressions — Desktop layout must remain untouched/unaffected by changes unless explicit permission is given. 6. No performance regressions — Maintain current page speed / Core Web Vitals scores on desktop pages. 7. Documentation — Brief before/after screenshots (or a short screen recording) for each page fixed, so we have a record of what changed. Again, no need to spend significant time on this. If the issues are fixed then thumbs up. 8.(Bonus) — Mobile pagespeed scores will be improved to the limit possible. Many take upwards of 3-4 seconds to first paint at this time. Requirements - Demonstrated hands-on experience with the Divi Builder. (not just general WordPress page-building experience) - Strong CSS skills for handling cases outside Divi's native responsive settings - Comfortable working within a staging environment (we'll provide a Cloudways staging URL — changes should be tested there before going live) - Portfolio examples or demonstration of past work showing mobile optimized Divi sites/pages - Good communication: We'll be checking in via Upwork messages as work progresses Deliverables - All pages display cleanly and professionally across standard mobile breakpoints - Desktop presentation unchanged - Site speed / Core Web Vitals scores maintained or improved - Short summary/documentation of changes made per page Timeline To begin as soon as possible. To Apply, Please Include - A short note on how you'd approach fixing responsive issues in Divi specifically - 2–3 links or examples of Divi sites you've made mobile-responsive - Confirmation you're able to work within a Cloudways-hosted staging environment
