WordPress Plugin Developer - Smart Contact Inbox for Contact Form 7

I need an experienced WordPress plugin developer to build "Smart Contact Inbox" — a plugin that turns the WordPress admin into an email-style inbox for Contact Form 7 (CF7) submissions. Overview: Every CF7 submission should be automatically captured, threaded by sender email, and displayed in a clean, Gmail-like interface — fully self-contained, no external services, no SMTP plugin, no paid add-ons. Core Features Required: 1. Centralized Inbox - All CF7 submissions in one place, grouped by form name 2. Threaded Conversations - Auto-group messages from same email into threads 3. Chat-style Thread View - Visitor messages left-aligned, admin replies right-aligned, with timestamps 4. Direct Reply - Reply to visitors from wp-admin using native wp_mail() (no SMTP plugin dependency) 5. Status Tracking - New / Read / Replied status indicators 6. Unread Badge - Real-time admin menu + admin-bar notification badge 7. Tags - Custom labels (Lead, Support, Spam, etc.) with one-click tag filtering 8. Saved Filters - Save & re-apply filter combos (form + tag + email + search) 9. CSV Export - Export current filtered inbox view 10. Filter & Search - By form name, tag, sender email, or keyword 11. Pagination - Performance for large inboxes 12. Bulk Delete - Multi-select conversation deletion 13. AJAX Replies - Send/save replies without page reload 14. Spam Shield - Silent honeypot trap (no CAPTCHA) + block domains/keywords 15. Settings Page - Toggle reply feature, customize reply subject format, override From email 16. Debug Page - Show CF7 raw field data, system status, one-click inbox test Requirements: - Proven experience building WordPress plugins (show past plugin work) - Strong knowledge of Contact Form 7 hooks/filters (wpcf7_mail_sent, etc.) - Experience with WordPress admin UI development, AJAX, and custom database tables - Clean, well-documented, secure code (proper sanitization/nonces) - Must be compatible with standard WordPress + CF7 setup, no third-party dependencies Deliverables: - Fully functional plugin (.zip, installable) - Basic documentation/readme - Code walkthrough or comments for future maintenance Please share links to similar WordPress plugins you've built when applying.
