What I'm looking for

I’m seeking a Business Development role, as stated in my professional objective, where I can apply my experience developing business and managing strategic accounts in oil and gas.

At Halliburton, I developed business in oil and gas, managing strategic accounts and commercial opportunities with customers including Petrobras and Petroecuador. As Country Sales Manager in Ecuador, I managed a US$30 million pipeline and closed a multi-year US$5 million contract with Petroecuador.

In 2025, I generated US$2.5 million in new revenue and achieved 58% year-over-year growth in Ecuador. I also supported Latin American sales teams with business strategies and commercial models.

Earlier at Halliburton, I managed well data quality and developed KPIs and reports using Landmark software, Java, and Crystal Reports XI. I also led a 10-person technical team and built experience across account management, sales, and data management.
