Matt provides dependable system administration services for organisations who don't need a full-time sysadmin or who need some additional infrastructure expertise. He generally works with small businesses, startups, and freelance developers, and he also work with larger companies initiating new projects. Matt works on a flexible part-time basis, and he offers ad hoc support for issues which 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 OS X and FreeBSD. 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, 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 costs and increased efficiency.
