What I'm looking for

I am looking for a role that values innovation and offers opportunities for professional growth in IT support and consultancy.

I am an accomplished Systems Support Administrator with over 9 years of extensive experience in system maintenance and technical support. My expertise lies in Active Directory and network security, where I have successfully implemented proactive monitoring systems using Zabbix, resolving 95% of potential system issues before they impacted operations. I take pride in enhancing system security through the deployment of PrivacyIDEA MFA, which led to a 30% reduction in unauthorized access incidents.

Throughout my career, I have consistently delivered comprehensive technical support, resolving 98% of client issues within SLA timelines to ensure business continuity. My strategic resource optimization on Hyper-V platforms has increased virtual server uptime by 25%. I am passionate about developing and maintaining documentation for IT systems, which enhances team knowledge and support efficiency. I am now seeking a Systems Administrator position where my skills in system support and IT consultancy can be leveraged to support your mission of maintaining optimal IT infrastructure and security.
