About

A little about me

I'm a Commissioning Manager with a proven track record delivering multi-million-pound projects covering commissioning of electrical substation HV equipment (GIS and AIS), MV and LV AC/DC distribution systems, metering systems, SCADA systems, and protection relay schemes — for transmission substations, wind farm substations, and data centre connection projects.

Having led technical projects from tendering stage through to project planning and execution, I collaborate closely with senior stakeholders, oversee multiple projects within a portfolio, lead portfolio project teams, and deliver client-focused results on time and within budget.
