WordPress Plugin Developer Needed - Must Show Real Plugin Portfolio | ($100/7 Days) - No WP Templates, Plugins Only -- 3

Critical requirement: I will only collaborate with developers who can demonstrate genuine WordPress plugin development experience. I need to see 2-3 actual plugins you've built from the ground up - not website templates, not theme customizations, not purchased scripts you modified. This project requires backend development skills, database architecture understanding, and API integration experience. Show me real plugin code you've written, or we can't move forward.


Budget: $100 fixed price limit for personal project
Delivery: 7 days
Updates: Daily progress reports required

Project Description
Building a WordPress plugin for semantic internal linking using AI embeddings and MySQL 8.1 VECTOR storage. This is NOT a keyword-based tool - it understands context to suggest relevant links between articles.

What makes this different: I have everything prepared - complete brief with UI diagrams, database schemas, code assembly strategy, and links to existing plugins you can reuse components from. You won't start from scratch.

The plugin needs:
OpenRouter API integration (embeddings)
MySQL 8.1 VECTOR similarity search
Admin metabox with suggestions + current links display
Bulk link insertion with checkboxes
Duplicate prevention and link tracking
Settings panel with API key configuration
Error logging and undo functionality

Tech stack: PHP 8.0+, MySQL 8.1 VECTOR, WordPress 6.0+, JavaScript/AJAX

Who Should Apply
Required experience:
Built WordPress plugins before (show me 2-3 actual plugins, not GitHub forks)
Comfortable with MySQL, wpdb, prepared statements
Knows WordPress security basics (nonces, sanitization, escaping)
Has worked with external APIs (REST calls, error handling)
Uses Cursor AI, Claude, or similar AI coding tools (vibe coding workflow)

Ideal candidate:
Created admin interfaces with metaboxes and AJAX
Understands vector embeddings concept (even if first time implementing)
Has Upwork/Freelancer reviews showing reliable delivery
Can work with detailed specs and adapt existing code

Red flags:
Only GitHub forks in portfolio
No reviews or first-time freelancer
Hasn't used AI coding assistants

Wants to rewrite everything from scratch instead of using provided resources

What I'm Providing You
Complete project brief (20+ pages)
UI mockups and data flow diagrams
Links to 3 WordPress plugins to reuse components from
Code snippets for critical functions (security, VECTOR queries, API calls)
OpenRouter API key
Wordpress site for testing

You'll assembly 60-70% from existing code, write 30-40% custom logic.
