My Shopify store, which offers professional services, is being crippled by a cluster of high-impact bugs. The checkout is the hardest hit—payment gateways refuse to complete, carts throw random errors, and the page occasionally stalls on a blank load screen. Product pages for my services are also flaking out: key information sometimes disappears or won’t update, and anything I tweak in the admin dashboard either fails to save or reverts after refresh. I need a Shopify expert who can jump in, locate the root causes, and deliver clean, fully tested fixes without disrupting live sales. A staging workflow is required so I can preview the repairs before we push to production. Deliverables • Diagnose and resolve all checkout failures (gateway authentication, cart logic, and page-load issues). • Restore full stability to service product pages, ensuring data renders and updates correctly. • Fix admin dashboard persistence problems so edits save first time, every time. • Supply a concise hand-off report outlining what was fixed, where, and how to roll back if ever needed. Acceptance Criteria The store must process a complete test order end-to-end with no errors; every service page must load with accurate content; and the admin must reliably save changes across several entries. If you’re confident you can hit those marks swiftly, I’m ready to start.
