🔧 Full-Stack WordPress Developer | Custom Themes & Plugin Development ⚡ Speed, Server & SEO Troubleshooting Specialist 🤖 Full-Stack & AI Engineer (React, Node.js, OpenAI API) ⭐ Top Rated | 100% Job Success Score | 200+ Projects Delivered Hi, I am a full-stack WordPress developer who builds and fixes everything from custom themes and plugins to server-level performance and SEO issues. Most of my work involves taking a slow, broken, or poorly structured WordPress site and turning it into something fast, stable, and properly indexed, or building a custom theme and plugin system from scratch when nothing off-the-shelf fits. I also work across full-stack web and AI development for clients who need more than WordPress can handle.
