What I'm looking for

I seek roles where I can improve system reliability and security, apply automation/AI, mentor teams, and contribute to operational efficiency in collaborative, growth-focused environments.

I am a senior IT specialist and systems administrator with over 20 years of hands-on experience managing end-to-end technical support, networks, and cybersecurity for multi-site environments.

I have managed 80+ workstations, 50+ mobile devices across six remote offices, and supported 200+ employees, achieving 99% uptime through proactive maintenance and troubleshooting.

I automate tasks using Python and AI tools (ChatGPT, DeepSeek, Gemini), built monitoring scripts that reduced manual work by 30%, and leveraged AI to cut task time by 20%; I also created and maintained company CMS platforms using WordPress and Joomla.

I lead internal security audits, configure firewalls/VPNs/cloud services, train large user groups on SAP ERP and system adoption, and maintain SQL reporting—combining technical depth with strong communication and training skills to improve operational efficiency and security.
