• Implemented and maintained Single Sign-On (SSO) integrations for 50+ enterprise SaaS applications weekly, including Salesforce, ServiceNow, and 500+ cloud-based platforms, leveraging Okta and Entra ID with SAML, OAuth 2.0, and OIDC to strengthen authentication security, enforce access governance, and enhance user experience.

• Managed and administered Microsoft Azure Entra-ID, including user provisioning and deprovisioning, RBAC, ABAC, and group management.

• Configured and managed Azure Active Directory (AD/Entra-ID) users, groups, and roles to control access to Azure resources.

• Redesigned enterprise identity architecture across on-prem Active Directory, Azure AD, and LDAP directories, shifting the organization from perimeter-based access to a Zero Trust model. Implemented Conditional Access, adaptive MFA, and risk-based authentication policies that reduced credential-based compromise attempts by 40% and improved access reliability.

• Automated full user lifecycle management for joiners, movers, and leavers, using PowerShell and Microsoft Graph API. Integrated with HR data flows to trigger provisioning logic via REST calls, dynamically enforcing role-based and ABAC policies, and updating security group assignments across hybrid AD environments.

• Implemented and maintained CyberArk Conjur, CyberArk PAM/EPM component EPV, PVWA, CPM, PSM, and PSM for SSH, AIM/AAM-CP/CCP, and PTA.

• Manage infrastructure secrets with CyberArk Conjur for applications onboarding, onboarding users, and deprovisioning, API Keys, secrets, and credentials management for DevOps operations.

• Monitor and review Privileged credentials activities using CyberArk’s Session Manager. (PSM)

• Integrate CyberArk with enterprise systems (Active Directory, SIEM, ServiceNow, Cisco Meraki, Network devices).

• Deployed and customized SailPoint IdentityIQ to unify identity governance across Active Directory (on-prem and Azure AD) and SaaS platforms. Built custom connectors for EHR, HRIS, and collaboration apps, enabling centralized access reviews and reducing orphaned accounts by 35%.

• Led enterprise-wide SSO modernization leveraging Azure AD and Okta as identity providers, integrating over 60+ applications (Workday, Bamboo HR, ServiceNow, Cerner, Epic, and Microsoft 365) with SAML, OAuth 2.0, and OpenID Connect, replacing legacy login methods and improving authentication success rates by 22% while maintaining HIPAA compliance.

• Instituted a Privileged Identity Management (PIM) and CyberArk framework for IT admins and third-party vendors. Enforced Just-in-Time (JIT) privilege elevation, vault-based credential rotation, and MFA reauthentication, cutting standing privileged accounts by 70% and achieving two consecutive zero-finding compliance audits.

• Engineered Conditional Access policies leveraging geolocation, device trust, and session behavior analytics. Built adaptive risk models that automatically block sign-ins from suspicious IPs and trigger step-up MFA for high-risk sessions, reducing unauthorized geographic access.

• ,Integrated Okta with Azure AD and configured Single Sign-On (SSO) for over 320+ apps using SAML, OAuth 2.0, and OIDC to enable seamless login and user experience. Deployed adaptive MFA and device-based Conditional Access aligned with PCI DSS 8, reducing authentication risks enterprise-wide.
• • Migrated over 20,000 on-prem Active Directory identities to Azure AD using Azure AD Connect with staged rollouts, synchronization rules, and attribute mapping for hybrid identity governance. Established federation trust between on-prem Active Directory and Azure AD, enabling seamless user access and centralized policy enforcement across hybrid workloads.
• • Successfully onboarded 1500+ Server Accounts, 600+ ESXI servers, and multiple SQL database servers into CyberArk, ensuring secure credential management and privileged access governance.
• • Maintain and patch CyberArk infrastructure components (Vault, PVWA, CPM, PSM).
• • Rotate and manage privileged credentials automatically to ensure password policy compliance.
• • Designed and deployed enterprise-wide Okta Adaptive MFA and Conditional Access frameworks, integrating risk-based policies, device compliance, and IP-based restrictions.
• • Configured and maintained CyberArk PAS solutions, focusing on Conjur for secrets management.
• • Automated lifecycle management using Okta Workflows and PowerShell, Graph API for provisioning, deprovisioning, & entitlements across HRIS, ServiceNow, and Azure AD cutting provisioning time by 60% and eliminating stale access.
• • Administered and governed privileged identities using CyberArk PAS, RBAC, ABAC and PIM, enforcing just-in- time (JIT) access, credential rotation, and monitoring for high-privilege accounts. Implemented access attestation, periodic reviews, and cleanup of dormant roles, ensuring full alignment with NIST SP 800-53 AC, ISO 27001, and SOX.
• • Partnered with SOC and IAM governance teams to investigate Okta system logs, sign-in telemetry, and anomaly detection events, building automated alerts for suspicious sign-ins and privilege escalations. Drove rapid incident triage and remediation processes that improved identity threat response times by 40%.

• Provided Tier 1 and Tier 2 technical support to over 2,500 enterprise users across corporate offices and remote branches, troubleshooting hardware failures, software conflicts, and network connectivity issues to maintain operational continuity and user productivity.

• Installed, configured, and maintained Windows-based desktop environments, mobile devices, and enterprise tools such as Microsoft 365, VPN clients, antivirus platforms, and remote desktop solutions, ensuring compliance with internal security and configuration standards.

• Monitored and managed IT assets including workstations, printers, and peripheral devices using centralized management tools, conducting preventive maintenance and reducing system downtime by over 25%.

• Documented incidents, root causes, and resolutions within ServiceNow and internal knowledge bases, improving issue resolution speed and reducing repetitive tickets by 30% through structured process documentation.

• Used ticketing systems to manage and process support actions and requests.
