RELEVANT EXPERIENCE

Responsibilities covered senior infrastructure support, complex fault diagnosis, systems deployment, resilience, technical change, stakeholder coordination and the resolution of business critical technology issues across large operational environments.

Practical involvement. Senior experience. Clear delivery.

MHY Consultant is built around working closely with the people responsible for delivering the operation. Depending on the requirement, that might mean supporting directors with strategy, working with managers to improve systems, preparing a business for audit, commissioning equipment, resolving a production issue or helping build an entirely new operating model.

The approach is deliberately practical. Understand the problem, establish what good looks like, build a workable plan and help deliver it.

Assignments can range from focused technical or operational support through to longer term projects and embedded senior leadership. The level of involvement is shaped around what the business actually needs.
