What I'm looking for

I seek a collaborative environment that fosters innovation and offers opportunities for professional growth in data science.

I am a Data Scientist with a solid background in Electrical Engineering, currently pursuing a postgraduate degree in Data Science and Analytics at the University of São Paulo. My expertise lies in pipeline automation, predictive analysis, and regulatory validation, particularly within the energy and utilities sectors. I am passionate about leveraging data to create scalable solutions that optimize operations and ensure compliance.

In my current role at Calden Consulting, I have successfully automated database auditing processes, boosting efficiency by 80%, and led regulatory compliance analysis, resolving 95% of dataset inconsistencies. My experience at CPFL Energy further honed my skills in ETL automation and data validation, where I developed interactive dashboards to monitor key indicators and mitigate regulatory risks. I am committed to delivering strategic insights that enhance decision-making and operational efficiency.
