Fintech SSO and identity for SaaS

The problem

Enterprise prospects in banking and insurance kept stalling at procurement. No SSO, no SCIM, no audit trail meant deals died in security review.

The solution

Built SAML and OIDC SSO with SCIM user provisioning, step-up MFA for sensitive actions, immutable audit log shipped to a separate account, and a self-serve admin console for tenant IT teams. Deployed across EU and US regions with data residency by tenant.
