What I'm looking for

I seek an operational IT role focused on systems administration, security, and scalable processes in a collaborative, growth-oriented team.

I am an IT executive and technology operations specialist with hands-on experience in system administration, network diagnostics, virtualization, and data protection. I have supported large user bases, managed Active Directory and operating systems, and implemented maintenance protocols that improved system stability and security.

My background includes internships in technical support and security consulting, where I resolved high volumes of tickets, enforced data safety compliance, and identified vulnerabilities. I hold a B.Sc. in Computer Science and multiple industry certifications, and I bring a practical, collaborative approach to IT operations and project delivery.
