I’m James, a Southern California-based lead web developer with 15+ years of experience building, optimizing, and maintaining complex web applications. I bridge the gap between low-level server environments and front-end user experience.
Rather than stacking dozens of heavy plugins, I write clean, maintainable PHP and JavaScript to keep sites fast, secure, and scalable.
My core work covers custom WordPress themes, bespoke plugin development, REST API integrations, and WooCommerce tuning. On the backend, I handle LAMP/LEMP server configuration, Nginx tuning, MySQL database optimization, and object caching. I also handle site reliability, security hardening, and zero-downtime staging setups.
Whether you need a dedicated senior partner to take full ownership of your web infrastructure or a reliable developer for custom builds, I bring clear US-time-zone communication, direct accountability, and senior-level execution.
Send me a message with details about your project, and let's discuss how we can get it solved.
