What I'm looking for

I seek a collaborative, business-focused analytics role where I can apply Python, SQL and ML to build decision-making solutions, communicate insights to stakeholders, and drive measurable process and revenue improvements.

I am a data scientist with a specialization in Data Science and practical experience applying Python, SQL and machine learning to commercial and financial problems. I focus on developing analytical solutions that improve processes and support decision-making.

I have built predictive and classification models in production-style projects, including a churn model with an F1-Score above 0.59, a prepaid-plan classifier with over 75% accuracy, and a linear regression solution to select the 200 most profitable oil wells using bootstrapped risk evaluation.

I pair technical skills (Pandas, NumPy, Scikit-learn, Plotly, Seaborn, Matplotlib, SQL, Git) with strong analytical thinking to translate business needs into actionable insights. I have experience working in collaborative, multidisciplinary teams and communicating technical findings clearly to non-technical stakeholders.

I hold a Bachelor’s degree in Business Administration and Strategy and completed a Data Science bootcamp to strengthen applied ML and analytics capabilities. I am committed to creating measurable value by aligning analytics with business goals and driving data-informed decisions.
