Architect phishing-resistant and passwordless authentication solutions using FIDO2/passkeys, Windows Hello for Business, certificate-based authentication, and other supported authentication methods.
Design and govern Privileged Identity Management (PIM) and privileged-access models to minimize standing administrative privileges and enforce just-in-time access.
Establish security architecture for workload identities, managed identities, service principals, application registrations, API permissions, and secrets/certificate management.

Design and review hybrid identity security, including Active Directory integration, Entra Connect/Cloud Sync, authentication flows, and protection of privileged identity paths.
Lead IAM threat modeling and security architecture reviews for new applications, platforms, cloud services, and major technology initiatives.
Identify identity-related attack paths, excessive privileges, legacy authentication dependencies, insecure application permissions, and other IAM security risks.
Design controls for detecting and responding to identity compromise, credential theft, token abuse, risky sign-ins, privilege escalation, and unauthorized access.
Define identity logging, monitoring, and alerting requirements and integrate Entra telemetry with SIEM/SOC and security operations processes.
Provide architecture and engineering leadership during complex identity security incidents and root-cause investigations.
Develop automation using Microsoft Graph API, PowerShell, REST APIs, and infrastructure-as-code/policy-as-code approaches to improve security consistency and reduce manual administration.
Lead IAM modernization, tenant consolidation, authentication modernization, application migration, and security-hardening initiatives.
Evaluate new Microsoft identity capabilities and recommend adoption based on security benefits, operational impact, architectural fit, and organizational risk.
Mentor IAM engineers and architects and provide technical leadership across IAM/security engineering teams.
