I am seeking an expert WordPress plugin developer to build a professional-grade, cross-browser cookie cleaner that gives administrators granular control over which specific cookies are deleted when users log out. This is not a simple "delete everything" plugin—existing solutions fail because they either rely exclusively on the Clear-Site-Data header (which does not work on Safari, iOS browsers, or Edge Legacy), or they lack a proper admin interface for selective deletion, or they cannot handle HttpOnly cookies (like WordPress authentication cookies) which JavaScript cannot touch. I need a four-layer hybrid solution that: (1) sends the Clear-Site-Data header only to supporting browsers (Chrome, Firefox, Edge Chromium), (2) performs server-side PHP deletion of HttpOnly cookies using wildcard patterns across multiple paths and domains, (3) executes JavaScript deep cleaning for non-HttpOnly cookies with aggressive domain/path fallbacks, and (4) includes special handling for Edge Legacy (non-Chromium), which has zero support for modern header-based clearing. The plugin must include a clean, intuitive admin settings page with a live cookie scanner, checkbox selection of individual cookies, wildcard pattern support, preset groups, and an exception list for cookies that should never be deleted. You must test thoroughly on Chrome, Firefox, Edge Chromium, and Edge Legacy—I will reject any proposal that ignores Edge Legacy or relies on a single method. Budget is $10–$20 USD, payment is milestone-based, and I am ready to hire immediately for the right developer who can demonstrate previous WordPress plugin experience, a clear technical plan, and a commitment to true cross-browser compatibility. If you understand the difference between Edge/ and Edg/ in user-agent strings and can explain how you will expire a wordpress_logged_in_* cookie across subdomains, I want to work with you.
