Research Data Analyst | Dataset Cleaning, Statistical Analysis & Reproducible Python Workflows

Profile Summary

I am a data analyst and data preprocessing specialist with hands-on experience transforming raw, messy datasets into clean, structured, and analysis-ready data for research, business intelligence, and machine-learning workflows. My core expertise lies in data cleaning, preprocessing, and exploratory analysis using Python (Pandas, NumPy), SQL, and Excel. I work extensively with real-world datasets that contain missing values, inconsistencies, outliers, and formatting issues, and I apply systematic methods to ensure data quality, reproducibility, and analytical reliability. I have worked on and completed multiple end-to-end data projects, including: Cleaning and preprocessing structured datasets for statistical analysis and machine-learning models Exploratory data analysis (EDA) to uncover trends, patterns, and anomalies Feature engineering and data transformation for predictive modeling Preparing research-ready datasets and documentation suitable for academic or industry use My project experience spans domains such as health data analysis (including sepsis datasets), retail and sales data, time-series analysis, customer behavior analysis, and socio-economic datasets. In research-oriented projects, I pay particular attention to methodological clarity, transparent assumptions, and reproducible workflows. From an academic perspective, I have experience conducting literature-driven empirical analysis, working with secondary datasets, and aligning data preparation with research objectives. I am comfortable supporting researchers with data preparation for theses, dissertations, and peer-reviewed studies. I value accuracy, pay attention to detail, and communicate clearly. I collaborate closely with clients to understand their research questions or business goals and ensure that the final dataset and analysis are aligned with those objectives. I am particularly well-suited for projects that require careful data handling, statistical reasoning, and dependable delivery.
