About Me

About Me

I am an experienced Process Engineer who has built a career at the crossroads of operation, technical, supply chain, and customer service.

I have led a business team of resin production over 4 years with a large group under supervision and my most recent achievement was the successful development, commissioning, and start-up of a Sulfur Trioxide unit for Infineum’s Additive Plant — the first-ever industrial application using pure oxygen (SafeTriox®).

My leadership philosophy is built on trust, boldness, and innovation, always challenging teams to exceed expectations. The strong sense of ethics and integrity instilled throughout my career in ExxonMobil continues to guide my decisions and actions.
