WordPress Developer for Startup

I run a startup called LensLink.io. Our website is built on WordPress using a HivePress template, but it also has custom code, plugins, APIs, and other integrations. We need someone who can understand the existing setup before making changes, because HivePress and the custom code can sometimes be tricky. We do NOT want someone who will make changes that break other parts of the site. Our main goal is to make the website very simple, smooth, and easy for users while making sure everything works reliably. We need help with things like: Fixing bugs and technical issues HivePress/WordPress troubleshooting PHP, JavaScript, APIs and custom code Listings loading and displaying correctly Image/video uploading, downloading and processing User accounts and listing workflows Payments and checkout Plugin conflicts Website speed and performance Making the overall user experience simpler Testing changes before they go live We want someone who can troubleshoot the entire flow of the website, understand how different parts connect, safely fix problems, and help improve the site over time.
