What I'm looking for

I seek senior engineering roles where I can lead plant design, commissioning and optimization projects, mentor teams, deliver measurable performance gains, and work with clients committed to safety, compliance and operational excellence.

I am a Senior Engineering Manager with deep expertise in process engineering, plant design and commissioning, having led multidisciplinary teams on gold processing and rare-earth feasibility studies. I drive projects end-to-end — from feasibility and simulation (METSIM, ASPEN) through PFDs/P&IDs, HAZOP, equipment selection and 3D modelling — ensuring regulatory compliance, safety and high quality execution.

Throughout my career I have moved from intern to foreman to senior leadership, improving plant performance and gold recovery, delivering conversions (Merrill Crowe to CIL), and consulting across retail, education and technology sectors. I prioritize client relationships, knowledge transfer and practical solutions that scale operations and maximize value.
