Introduction

Jan Paolo Gabriel Supena

WordPress platform administrator and Senior Web Developer with extensive experience building, maintaining, integrating, and operating production WordPress, WooCommerce, and CMS-driven websites. I use AI-assisted workflows for technical planning, debugging, code review, QA checklist creation, documentation, migration planning, and faster investigation of logs, plugin conflicts, and integration issues while retaining human review for security, accuracy, and production stability.

My background combines hands-on PHP, JavaScript, MySQL/MariaDB, HTML/CSS, and Git development with operational ownership across Linux hosting, Apache, Nginx, Plesk, Cloudflare, DNS, SSL, caching, redirects, uptime-sensitive troubleshooting, and client-facing technical support.
