What I'm looking for

I'm seeking a senior technical role focused on Active Directory, PKI, and hybrid identity where I can lead escalations, mentor engineers, create readiness content, and drive customer-centric solutions in a collaborative, security-focused environment.

I am a results-driven IT professional with 9+ years specializing in Active Directory, PKI, hybrid environments, and enterprise networking. I deliver SME-level troubleshooting and have a proven record resolving complex authentication and certificate issues for global enterprise customers.

At Microsoft I coached delivery partner engineers, led escalation management, and created technical readiness content on PKI, TLS, and certificate-based authentication. I combine hands-on case ownership with collaboration across Product Groups to improve supportability and customer outcomes.

I am bilingual in English and Spanish, hold Azure and security certifications, and enjoy mentoring technical teams to close skill gaps. I seek roles where I can lead technical initiatives, drive incident resolution, and build training that raises team capability and customer satisfaction.
