WordPress Developer for Website Optimization

Need a WordPress developer to optimize a high-usage website and improve site performance and infrastructure. Tasks include replacing WP cron with a real cron, limiting WordPress Heartbeat frequency, enabling browser caching and gzip compression, using caching plugins like WP Super Cache, removing unused themes and plugins, and updating remaining components to the latest stable versions. Also need help securing the site by adding .htaccess rules to block bad bots, malicious traffic, and XML-RPC access, plus hiding the WordPress login page.
