What I'm looking for

I am looking for a role with a growing MSP where I can strengthen service delivery, improve security, and help the technical team scale. I am also open to an in-house IT position where I can take ownership of infrastructure, cybersecurity, incident response, and system availability. I bring hands-on experience across technical support, systems architecture, automation, and development, with the range to solve immediate problems while improving the environment over time.
