CETRE SysAdmin Services

Matt provides dependable sysadmin, devops and cloud engineering services for organisations who don't need a full-time sysadmin or who need additional infrastructure expertise. He often works with smaller businesses and startups, and he also works with larger companies initiating new projects. Matt operates on a flexible part-time basis, and he offers ad hoc support for issues that arise outside normal working hours. He offers a flat hourly rate for ongoing work, and he can provide one-off consultancy for a bespoke fee.

Matt works mainly with Linux and other Unix-like systems such as BSD. He has extensive experience with many technologies in a wide range of industries, which enables him to assess the bigger picture in any existing or planned infrastructure. He can rearchitect as needed, optimising for cost, security, stability and performance, before fine-tuning the details and implementing the best solutions.

Matt mainly works with cloud computing infrastructure and he specialises in Amazon Web Services and Google Cloud Platform, though he is also very experienced with administration of physical hardware. He believes strongly in the devops philosophy of working closely with developers to utilise as much automation as possible for reduced overheads and increased efficiency.
