About me
IT infrastructure engineer with 10+ years in IT outsourcing, working on production networks and servers daily.
I design, configure and secure networks end-to-end — home to full corporate — on Cisco, HPE, UniFi, Ruijie and more. I also run Linux and Windows infrastructure (AD, PKI/CA, DFS, Docker), configure firewalls, and handle hosting, domains, email, Microsoft 365 and Google Workspace. And I deliver professional penetration testing with clear, actionable reports.
Whatever the IT problem is, I've likely solved it in production. Clean docs, straight talk. Message me before ordering.
