What I'm looking for

I seek a hands-on IT/security role where I can manage systems, improve data workflows, lead incident response, and grow in cybersecurity practice.

I am a detail-oriented IT and cybersecurity professional with over five years of combined experience in technical support, data management, and system administration. I focus on building secure, efficient workflows and optimizing enterprise systems for performance and compliance.

My background includes SQL Server and Oracle database management, Power BI reporting, SharePoint and Teams administration, and incident response and digital forensics. I have led teams, administered access controls, and delivered data-driven assessments to improve system integrity.

In my capstone project I designed and configured enterprise IT systems, implementing database administration, access control, and workflow automation to enhance organizational efficiency and security. I bring practical field experience supporting large facilities and a strong commitment to documentation, training, and continual improvement.
