What I'm looking for

I seek a data-focused role where I can apply ML and visualization skills to drive measurable impact, in a collaborative, growth-oriented team.

I am a Data Scientist with over five years of experience applying advanced statistics, machine learning, and data storytelling to inform strategic decisions and optimize processes.

I have led reporting and visualization efforts, generated actionable insights from field data, and presented findings to senior stakeholders to support operational improvements.

My technical toolset includes Python, R, SQL, Tableau, Power BI, Scikit-learn, TensorFlow, XGBoost, Snowflake, Postgres, MLflow, and deployment tools such as AWS SageMaker and GitHub Actions.

I deliver measurable results — including a sales forecasting model that improved performance by over 15% and a real-time Tableau dashboard — and I collaborate effectively in teams while contributing to open-source data-cleaning tooling.
