WordPress Developer for Website Troubleshooting

Need a WordPress developer to troubleshoot and fix a slow, unstable website. The site frequently experiences “Error establishing a database connection” and “504 Gateway Time-out” issues, along with very slow page load times. The goal is to identify the root cause, improve performance, and stabilize the site during a two-week contract. Experience diagnosing server-side and WordPress-related issues is important for this short-term project.
