Research & Data Analyst | Statistics | Economic | Policy | Market

Need research that is not only thorough, but actually useful for decision-making? Iโ€™m a Research & Data Analyst with 8+ years of experience and 120+ completed projects across policy, market, economic impact, financial, sustainability, and academic research. I help clients turn complex data, documents, and market information into clear findings, defensible analysis, and professional reports. My work ranges from economic contribution studies and policy analysis to market research, financial analysis, statistical modelling, geospatial analysis, and multilingual text analysis. I regularly work with government data, administrative records, financial statements, survey datasets, market intelligence, and qualitative evidence. Depending on the project, I apply methods such as t-tests, chi-square tests, correlation analysis, linear and logistic regression, modified Poisson regression, survey-weighted analysis, interaction analysis, sensitivity testing, input-output modelling, PLS-SEM, and geospatial analysis. What I can help you with: Policy & regulatory research | Market & competitor research | Economic impact analysis | Financial research | Statistical analysis | Survey analysis | Geospatial analysis | Literature reviews | Multilingual text analysis | Technical reporting Tools: Stata, Python, Pandas, Excel/Google Sheets, SPSS, SmartPLS, GeoPandas, Matplotlib, Semrush, XLM-RoBERTa, along with AI-assisted research and analysis tools that help streamline research, analysis, and reporting while maintaining careful review, validation, and source traceability. My focus is simple: accurate analysis, transparent methods, strong source traceability, and outputs that are clear, practical, and ready to use.
