What I'm looking for

I’m looking to lead ISO 50001-driven energy and sustainability programs across multi-site operations—owning benchmarking, reporting, and smart metering—while partnering with leadership to turn variance insights into real efficiency and cost outcomes.

I’m an Energy & Sustainability Manager with 7+ years of experience in multi-facility energy management, with a proven ability to deliver measurable efficiency, compliance, and operational improvements. As a Registered Energy Manager (REM Type 2), I focus on ISO 50001 execution, energy audits, procurement, and performance reporting for energy, water, and waste.

Across multiple manufacturing and industrial sites, I build structured energy benchmarking and reporting frameworks, integrate smart energy technologies, and lead variance analysis that I present to senior leadership. I’ve driven improvements through metering strategy, forecasting, and data-backed interventions—coaching engineers and operations teams to scale practical energy conservation initiatives.

In recent roles, I led utility account operations and sustainability and resilience strategies aligned with ISO 50001, and I managed end-to-end energy and utilities setup for a new factory, including utility contract review and commissioning readiness. My core approach is clear: translate technical data into actionable decisions that reduce energy intensity, optimize costs, and strengthen statutory and regulatory compliance.
