What I'm looking for

I'm seeking technical roles (Data Scientist/Analyst/Engineering) focused on building models, end-to-end pipelines, and delivering measurable business impact in collaborative, growth-oriented teams.

I'm a Data Scientist and Data Analyst focused on solving technical problems through data analysis, machine learning, and statistical modeling. I build end-to-end data pipelines, develop ETL processes, and create dashboards and predictive models using Python, SQL, pandas, NumPy, scikit-learn, and TensorFlow.

With a background in marketing and web development, I translate business requirements into data-driven solutions, have led analytics and web projects producing measurable results (e.g., e-commerce revenue and recurring site traffic), and coach learners as a private tutor while completing an intensive Data Science bootcamp.
