Hire the Best AJAX Developers
in the United States
San Diego, California
I'm a web developer with over 20 years of experience building, maintaining, and troubleshooting websites and custom web applications. I specialize in WordPress development, including custom plugins, custom themes, and Advanced Custom Fields (ACF). I also handle third-party integrations and inherited websites with complex or unfamiliar codebases. I'm particularly skilled at diagnosing obscure bugs, resolving display and functionality issues, and finding practical solutions that other developers have struggled to identify. Beyond WordPress, I also build custom PHP and JavaScript applications like calculators, reporting tools, billing interfaces, and API integrations using PHP, MySQL/MariaDB, JavaScript, React, and HTML/CSS. I've worked with clients in eCommerce, education, nonprofit, fulfillment, and other industries. Whether you need a custom feature, an API integration, or help tracking down and solving a difficult technical problem, I provide careful, production-ready work with an emphasis on reliability and maintainability. I'm a particularly good fit for projects where the problem is difficult to explain, the code is unfamiliar, or an off-the-shelf plugin or solution cannot provide the required functionality.
