WordPress Developer | Custom Plugins, WooCommerce & API Integration

WordPress Developer for custom plugins, PHP, WooCommerce, API integration, performance optimization, and technical troubleshooting. I help businesses make existing WordPress systems faster, more reliable, and easier to maintain. My approach combines custom WordPress development + technical problem-solving. Before changing code, I review the existing site architecture, plugins, theme, database, hosting, integrations, and business requirements.
