Develop a Custom WordPress Shortcode Using PHP and WP_Query

I need a WordPress developer to create a lightweight custom shortcode that dynamically displays recent posts on an existing page. The shortcode should: * Retrieve posts using a custom WP_Query * Display the featured image, title, excerpt, date, and link * Accept parameters for category and number of posts * Produce a responsive three-column layout * Show a suitable message when no posts are available * Escape output and follow WordPress coding standards * Work without installing an additional plugin * Include brief instructions explaining how to use the shortcode Example usage: [recent_posts category="news" limit="3"] This is a focused customization for someone experienced with WordPress, PHP, shortcodes, and responsive CSS. Required skills: WordPress, PHP, WP_Query, Shortcode API, HTML, CSS Budget: €10 fixed price
