Turning Data into Actionable Insights
Passionate about data analysis and problem-solving, I help companies make informed decisions by transforming raw data into meaningful insights.
From Quality Improvement to Data-Driven Strategy
In the automotive electronics industry, I led in-depth data analyses and developed clear visualizations that improved process efficiency and product quality. My work played a key role in refining anomaly detection and optimizing workflows.
Expanding My Knowledge
To strengthen my skills, I completed an intensive data analyst training program, where I deepened my knowledge in Business Intelligence, Machine Learning, and Text Mining, while refining my expertise in SQL, Python, and data visualization.
Seeking New Challenges
I am eager to apply my expertise in a dynamic environment where data-driven decision-making is essential. I am particularly interested in leveraging analytics to drive business performance and operational excellence.
