Problem
Dealerware’s identity layer was a legacy, non-standardized Devise/JWT setup. Every new OEM partner (Nissan, then others) meant custom auth code — slow to ship, risky to maintain, no clean path to add identity providers.
Action
Designed and built the migration to Auth0 + SAML from the ground up as a provider-agnostic architecture: one integration layer, not one-off code per partner.
Result
33,000+ users onboarded through the new system on the Nissan rollout alone. Five additional identity providers added afterward with zero relevant code changes — configuration only. Zero downtime during the migration.
