What I do

Identity Architecture

Target-state design across CIAM, workforce IAM, and privileged access — authentication flows, user stores, API integration, and multi-tenancy patterns.

Platform Migrations

Large-scale identity platform migrations — user migration strategies, integration cutover, co-existence models, and zero-downtime rollover.

Integration & Automation

Lifecycle automation via Okta Workflows, SailPoint connectors, SCIM, and custom orchestration across HRIS, ITSM, and cloud infrastructure.

Strong Authentication

Passkeys, TOTP, native push, identity verification, and adaptive MFA — phishing-resistant strategies tailored to organisational risk appetite.

Identity Governance

Access certification campaigns, RBAC design, joiner-mover-leaver automation, SoD policy enforcement, and compliance posture uplift.

Privileged Access Management

CyberArk and BeyondTrust implementation, automated credential management, session monitoring, and application onboarding at scale.
