What I'm looking for

I’m looking to lead energy and decarbonization programs that cut emissions and costs, drive circular economy outcomes, and strengthen compliance—working closely with stakeholders to turn data analysis into measurable sustainability results.

I’m a results-driven Energy Management Coordinator with 10 years’ experience optimizing energy usage, reducing costs, and strengthening environmental management. I’ve developed contingency planning for environmental emergencies, and I conduct energy and environmental performance analysis to translate data into action and results.

At Debswana Jwaneng Mine, I progressed from Energy Manager to Energy Management Coordinator and deliver mine-wide energy and decarbonization strategy aligned to sustainability goals and national energy policies. I implement renewable integration (including solar), run energy audits using regression-based performance targeting, and lead carbon reduction and circular economy initiatives—supported by stakeholder engagement, training, and ISO compliance for environmental management systems.
