I am expanding a fast-growing digital platform and need a WordPress-based CMS that remains rock-solid when traffic spikes and product counts soar. The heart of the job is building truly dynamic content types: custom taxonomies and Advanced Custom Fields must work together seamlessly so editors can spin up new product categories, landing pages, and resource hubs without touching code. To make that possible, extensive PHP work sits behind the scenes—far beyond theme tweaks—so the solution stays modular and clean for future feature drops. The system must also speak fluently with WooCommerce, PrestaShop, and Magento, allowing product data, orders, and inventory to flow in both directions. Everything runs on cPanel, so deployment scripts and server settings have to feel native there. Key deliverables 1. A custom content framework (post types, taxonomies, ACF configs) packaged as a reusable plugin. 2. Solid, documented integrations that sync core data across WooCommerce, PrestaShop, and Magento without slowing the site. 3. Optimised server configuration on cPanel capable of handling high concurrency and large catalog searches. 4. Technical documentation and a short hand-over call so my in-house team can extend the build safely. Acceptance criteria • New content types can be created and managed from the dashboard with zero code. • Integrations pass load testing at scale and recover gracefully from API hiccups. • Page loads remain under sub-second for catalog pages with 10k+ products. • Codebase follows WordPress and PSR-12 standards and is version-controlled in Git. If you thrive on deep WordPress architecture, heavy PHP customisation, and multi-platform eCommerce workflows, this project should feel like home.
