URGENT: Wordpress Developer for Site Repair

My WordPress site is suffering - I need a deft touch from an experienced professional to resolve broken site, decrease loading speeds and troubleshoot database connection errors and timeout issues. Your application must demonstrate your prior relevant work. This project doesn't require adherence to a specific style theme, but a keen eye for clean and functional design would be a plus. If yo've worked with Spinup WP, it's HUGE plus.

Looking for a WordPress developer with:
- Excellent troubleshooting capabilities
- Proven experience in optimizing slow loading sites
- Past work portfolio demonstrating similar projects completed

I am open to discussion on the best strategies to fix these issues. Only experienced WordPress developers who can deliver quality work need apply.
