A data science specialist for clients who need evidence, not guesswork.
I combine Python, statistics-minded analysis, machine learning, visualization, and SQL. My goal is not only to deliver code, but to make the data path clear from raw input to documented insight.
Data profile
Focused on clean data, useful models, and results clients can understand.
I work with datasets that need structure, analysis, modeling, visualization, or SQL-based exploration before they can support decisions.
- I turn broad data questions into a precise analysis or modeling scope.
- I use Python, Pandas, NumPy, Scikit-learn, SQL, Excel, Power BI, Git, and LLM-aware workflows where they fit the task.
- I document assumptions, cleaning steps, model behavior, query logic, and delivered results.
