What I'm looking for

I’m looking to progress into technical or project-focused roles, applying my analytical, adaptive, and communication skills to deliver impactful solutions in manufacturing and process optimization.

At ExxonMobil Kuala Lumpur Technology Centre, I developed process and thermodynamic-based models to evaluate system behavior and support optimization initiatives that reduced catalyst consumption by USD 2M/year.

I also performed process simulations and material balance evaluations, and led troubleshooting and root cause investigations to improve process stability. My process optimization initiatives delivered more than USD 10M in total value.
