What I'm looking for

I am seeking a hands-on IT role focused on secure infrastructure, endpoint and identity management, with opportunities for impact, learning, and cross-team collaboration.

I am an analytical and reliable IT professional with a Bachelor of Science in Computer Science and broad experience across systems administration, security, and database management. I focus on delivering secure, resilient infrastructure and measurable operational improvements.

At my current role I implemented Veeam backups achieving a 99.9% recovery success rate and deployed layered endpoint security that reduced malware infections by 50%. I also built a centralized patch management approach reaching 95% compliance across 400+ endpoints.

Previously I led the work-from-home transition securing 1,500+ endpoints, maintained inventory for 3,000+ assets, and performed extensive security audits, device hardening, and risk analyses to strengthen operational security posture.

I bring strong customer orientation, an ITIL/Agile mindset, Identity and Access Management experience (SSO, SAML, LDAP, Zero Trust), and a collaborative approach to solving complex technical problems while improving efficiency and compliance.
