Deployments across many WordPress sites are hard because each site is “slightly different.” I built a workflow that treated deployment like a checklist-driven pipeline: pre-flight validation, reliable backups, a controlled change step, verification checks (forms, key pages, and error signals), and clear rollback triggers when verification failed. The technical focus was sequencing and isolation—making sure changes were applied consistently while respecting stack differences—so shipping improvements didn’t require manual babysitting site by site.
