About
I am a results-driven Project Manager and Mechanical Engineer with over 10 years of experience delivering sustainable energy, HVAC, and mechanical projects across New Zealand, Sweden, and Norway. I hold a Master of Science in Sustainable Energy Systems and have a strong track record of managing multidisciplinary teams, contractors, budgets, and end-to-end project delivery in technical and safety-critical environments. My technical strengths include CAD, CFD, and system optimisation.
I am a New Zealand permanent resident and will soon be relocating to my newly built home in Kaiapoi.
I excel at turning complex challenges into practical, buildable solutions, leading diverse teams, and communicating clearly with stakeholders at all levels. I bring hands-on engineering and maintenance experience across propulsion, electrical, and safety systems, combined with a strong focus on indoor climate optimisation. I am motivated to apply my blend of technical expertise, project leadership, and educational experience to energy and HVAC projects that deliver long-term value and measurable impact.
