Recommendations from colleagues and clients across IT infrastructure, data engineering and compliance projects.
"I had the pleasure of working with Luke delivering a PCI compliance project for an organisation up against a tight time deadline. Luke was extremely knowledgeable and easy to get on with. His PowerShell scripting offered up innovative solutions. His ideas were pragmatic and based on actual real IT experience which is rare these days."

"I worked with Mark on a complex financial reporting project. His attention to detail is second to none. He was open to suggestions, able to follow ideas through and clearly explain why something would or wouldn't work. He was supportive of test and would point me in a new direction if new development warranted it."
