Manufacturing finance executive at ENNOVI, improving financial results across two plants and defining a structure for growth.

Mexico
Message

At ENNOVI, I was responsible for financial results, operational variances, forecasts, and standard cost definition across two manufacturing plants in Zapopan. I also helped define a structure to support the growing operation and improve plant results.

At Molex, I reorganized the finance team and implemented a cost structure that distinguished results across nine divisions. I reduced cost variation in the most critical areas by up to 30%, helped improve the plant’s profit margin from negative in 2021 to positive 20% in early 2024, and led differentiated budgeting that achieved 87% compliance.

Earlier at Molex, I managed plant cost structures and developed automated reporting with Power BI and Excel. My background also includes SAP finance implementation, data analysis, and manufacturing finance; I hold an MBA focused on operations management and a master’s degree in data science.
