Hi, I can help you keep both your MERN and WordPress products polished, stable, and consistent without disturbing existing functionality. The hidden challenge here isn’t just fixing UI issues , it’s understanding legacy patterns fast enough to make clean changes that blend into the current design system. With 15+ years in React.js, Node/Express, MongoDB, and WordPress theme/template work, I’m used to jumping into live codebases, tracing frontend issues quickly, and improving responsiveness, spacing, rendering, and cross-browser behavior with minimal risk. I work carefully with HTML5, CSS3, JavaScript, Tailwind/Bootstrap, Git, and deployment workflows to ensure each fix is tested and safe. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If helpful, I can start by auditing the most visible UI inconsistencies, then work through them in priority order. Are the MERN and WordPress projects sharing any common design system or component rules that I should follow for consistent UI fixes? I’d also like to understand how you currently manage UI changes between the MERN app and WordPress side, and whether there are any design rules or component libraries I should follow. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad
