About me

IAM consultant specialising in post-merger identity. I merged two Okta orgs into one: 150+ apps, full user base, LDAP source migration, no cutover downtime. Also HRIS-driven lifecycle automation via SAML, SCIM and Workflows. Fixed-scope engagements, remote from Slovenia.

Okta Identity Platform & IdP Consolidation
Deep expertise in Okta SSO, Lifecycle Management, Workflows and org-to-org migration. Proven track record of merging two Okta orgs across a 2,000-person global organisation, migrating 150+ applications and the complete user base, resulting in a single identity plane across 300+ applications on SAML, OAuth and SCIM.

M&A Identity Integration & Day-1 Planning
End-to-end M&A identity readiness assessments covering app inventory and overlap, IdP consolidation options, HR-to-IdP source of truth decisions, Day-1 access planning and sequenced integration roadmaps. Hands-on execution of cutover waves and rollback paths for large-scale post-merger integrations.

Joiner-Mover-Leaver Automation & HRIS Integration
Design and implementation of HRIS-sourced user lifecycle automation: automated provisioning and deprovisioning into Okta and downstream tools via SCIM, SAML, API and workflow automation. Access follows the HR record, eliminating manual ticket-based processes.

Cloud & On-Premise Infrastructure
Hands-on experience with GCP, AWS, Azure and on-premise datacentres. Application of Terraform and CI/CD pipelines for controlled IAM and infrastructure change management.

Endpoint Management & MDM Consolidation
Multi-environment endpoint consolidation using Kandji, Jamf and Intune at 2,200+ device scale. Led vendor selection and migration of four inherited MDM environments into a single managed estate.

SAML, OAuth/OIDC, SCIM & LDAP
Broad protocol expertise covering SAML, OAuth/OIDC, SCIM and LDAP for federated identity, app integration and directory source strategy across complex multi-org environments.

Google Workspace Administration
Organisation-level administration of Google Workspace at 2,000+ person scale, including onboarding and offboarding workflows across 15 EU offices.
