I have professional experience in Data Collection, Data Cleaning, and Data Analysis, delivering accurate, structured, and insight-driven results for academic research, business intelligence, and decision-making projects. My work involves collecting quantitative and qualitative data from multiple sources including surveys, questionnaires, interviews, secondary datasets, and digital records, ensuring data validity, reliability, and ethical compliance. I specialize in cleaning and preparing raw data by identifying and correcting errors, handling missing values, removing duplicates, managing outliers, and standardizing formats to ensure high-quality datasets ready for analysis. Using advanced analytical techniques, I perform quantitative analysis such as descriptive statistics, regression analysis, hypothesis testing, and trend analysis, as well as qualitative analysis including thematic coding, content analysis, and mixed-methods research. I utilize industry-standard tools such as Power BI, Excel, SPSS, STATA, Python, and NVivo to analyze data efficiently and accurately. My expertise includes data visualization and dashboard creation, transforming complex datasets into clear, interactive charts and reports that support strategic decisions. I also develop data scripts and automated workflows using Python and Excel to improve efficiency, reproducibility, and scalability of analysis processes. Throughout my work, I focus on delivering clear insights, well-documented outputs, and actionable recommendations, while maintaining strict data confidentiality and quality standards. This experience allows me to support businesses, researchers, and organizations with reliable data solutions that drive performance, research quality, and informed decision-making.
