Multi-Tenant LMS Platform at Scale

Per-client WordPress installs do not scale to a fleet, so I rebuilt the platform as a single codebase with database-switched tenancy: one Docker image, a per-tenant Redis prefix, deployed across more than 30 servers. It grew to 127 enterprise tenants and over 125,000 registered users across sectors from postal and banking to healthcare and manufacturing. Behind it sat 35 custom plugins and a request-aware plugin loader that swapped the active set per request to keep WordPress boot times low.
