At The Office for Environmental Protection, I managed delivery of a combined procurement and finance system, including its implementation and staff training. The project was delivered on time and within budget, with over £100,000 in contract value savings reinvested in a new apprenticeship scheme.

At Information Commissioner's Office, I project managed a new procurement and finance portal, delivered on time and within budget, and achieved £145,000 in contract value savings. I'm MCIPS-qualified and have worked across central government, the NHS, and private sector clients.
