@divyabalasubramanian

I build and operate enterprise IAM platforms for secure identity access at scale.

I've delivered IAM authentication, federation and production operations across IBM India public-sector engagements, supporting ISVA and ISIM with zero SLA breach. I build SAML, OAuth 2.0 and OIDC SSO, custom InfoMap authentication flows, MFA, SCIM provisioning and resilient reverse-proxy environments.

Previously at Capgemini and TCS, I managed identity lifecycle and governance for 600K+ identities across logistics and banking environments. I've led access certifications, platform upgrades, DR testing, vulnerability remediation and audit-ready operational reporting across IBM Security, SailPoint and Microsoft Entra ID.
