WordPress Support & Advanced Enterprise Portal Development

Description

Comprehensive long-term support and advanced development for a large-scale corporate portal built on WordPress. The project focuses on continuous infrastructure evolution, implementing complex business logic via PHP and JavaScript, and creating a seamless content management experience. We implemented a sophisticated multilingual architecture using Polylang Pro, including a custom-built integration for ACF Pro. This solution streamlines the localization process by allowing the export and import of custom fields via XLIFF format, ensuring efficient translation workflows. By bridging high-performance frontend engineering with robust backend architecture, we ensured the portal remains scalable, secure, and fully aligned with the brand's digital marketing goals. A standout feature is the custom-built administrative module that automates design workflows: it allows managers to generate marketing banners directly in Figma using predefined data combinations and strict input validation. To maintain a competitive edge, we conducted deep performance optimization, achieving top-tier Google PageSpeed scores through advanced caching, asset minification, and code refactoring. Our approach emphasizes clean code standards and high-speed performance to meet the demands of a high-traffic corporate environment.
