What I'm looking for

Seeking an opportunity to apply analytical skills to support data-driven decision-making.

As a seasoned data analyst with a strong background in geological engineering, I leverage my expertise in data preparation, visualization, and delivering actionable insights to drive business growth. With a solid foundation in Python, SQL, and statistical analysis, I have successfully developed machine learning models that optimize operational parameters and facilitate data-driven decision-making.

Throughout my career, I have worked on various projects, including predicting oil reserve volumes, gold extraction amounts, and user orders for ride-hailing services. My experience in designing and creating databases, interpreting complex data, and presenting insights to executives has equipped me with the skills to support data-driven decision-making.

I am passionate about applying my analytical skills to drive business growth and am excited to explore new opportunities that align with my expertise.
