What I'm looking for

I seek senior engineering or estimation roles where I can lead multidisciplinary teams, manage large tenders and deliver complex onshore/offshore or mining projects with strong technical and commercial impact.

I am a seasoned mechanical engineer with over 38 years' experience across heavy engineering sectors including oil & gas, refineries, petrochemical plants, mining and material handling. I have led estimation and project teams, coordinated multidisciplinary disciplines, prepared technical and commercial proposals, and managed construction, commissioning and refurbishment projects internationally.

My career highlights include senior roles in estimation and construction management, delivering multi‑million dollar projects, developing execution plans and QA systems, and supervising mechanical works for major refineries and mining concentrators. I bring practical onshore/offshore site experience, strong costing and tendering expertise, and a commitment to safe, standards-driven project delivery.
