Headless CMS Integration & React Website Enhancements

Hi, I have an existing React/Next.js website that needs some improvements and better content management, and I'm looking for someone experienced with React and headless CMS integrations. Here's what I need: Headless CMS integration — connect the existing frontend to a suitable Wordpress CMS so I can manage things like pages, sections, images, and other content without needing to edit the code every time. API / data integration — connect the required APIs and make sure content is being fetched, updated, and displayed correctly throughout the application. UI improvements — there are a few existing screens and components that need visual and UX improvements, including spacing, responsiveness, layouts, and general consistency. Frontend refinements — clean up any existing React/Next.js issues and make sure the implementation remains fast, responsive, and maintainable. Developer-friendly setup — I want the CMS and frontend structured properly so it's easy to continue adding and managing content later. The existing frontend is already underway, so I don't need someone to build an entire application from scratch. The main goal is to improve what's already there, integrate the CMS/API layer properly, and leave everything working reliably. Please share examples of similar React/Next.js, API, or headless CMS work you've done. I'm looking for someone who can understand an existing codebase and make clean, practical improvements rather than overcomplicate things. The project involves implementing CMS-driven content, connecting the required APIs, improving the existing UI, and ensuring everything remains responsive and easy to manage. The frontend is already underway, so the focus is on clean integration and targeted improvements rather than building everything from scratch.
