I'm a Top Rated Data Analyst on Upwork with over five years of hands-on experience in econometrics, biostatistics, statistical analysis, and forecasting. I've worked with PhD researchers scrambling before their defense, policy teams who needed econometric data analysis that could survive a room full of critics, and healthcare professionals whose clinical data analysis had to meet journal standards before submission. In every case, the goal was the same: to get the data analysis right, explain it clearly, and make sure it holds up. ⤷ Top-rated Data Analyst on Upwork ⤷ 46+ completed data analysis projects ⤷ 100% Job Success Score ⤷ Certified: Data Visualization with R (IBM) | R for Data Science (IBM) | Google Analytics Here's what I've learned after five years of data analysis work: Most projects don't fail because of bad data. They fail because the wrong question was asked, the wrong model was chosen, or the assumptions were never checked. That's the gap I close. Before I run a single test, I make sure I understand your research question, your dataset, and what your results actually need to prove. What I do for you I handle the full data analysis process — from messy raw data to clean, documented, publication-ready results. Depending on your project, that means: As your Data Analyst for academic and dissertation work, I support Chapter 3 from start to finish — research design, data preparation, model selection, assumption testing, results interpretation, and write-up in language your committee will accept. As your Data Analyst for econometric and policy research, I build models for program evaluation, policy impact, and causal inference — OLS, IV, difference-in-differences, panel data analysis with fixed and random effects, and time series data analysis with ARIMA, VAR, and cointegration testing. As your Data Analyst for biostatistics and healthcare research, I deliver clinical data analysis to publication standard — survival analysis, Cox regression, Kaplan-Meier curves, longitudinal data analysis, and multilevel modeling for health datasets. As your Data Analyst for business and financial projects, I provide data analysis that supports real decisions — predictive modeling, financial forecasting, regression analysis, and business intelligence reporting that goes beyond surface-level dashboards. Every data analysis engagement is delivered with reproducible, well-documented code in R, Stata, Python, or SPSS — so your results can be verified, defended, and built upon. Data Analysis Tools: R | Stata | Python | SPSS | SAS | EViews | Excel Whom I work with I work best with people who take their data analysis seriously. That includes PhD and Master's students whose dissertation data analysis needs to withstand a defense, economists and policy analysts who need econometric data analysis that holds up under scrutiny, healthcare and clinical researchers whose data analysis has to meet peer-review standards, and businesses or financial teams who need data analysis that actually informs decisions. If you're not sure whether your project fits — ask. I'll tell you honestly. What makes my data analysis different I don't finish a data analysis and go quiet. I tell you what the results mean, what they don't mean, and what someone might challenge — before they do. If an assumption is violated, I flag it and fix it. If a simpler method gives you a more defensible answer, I'll recommend it even if it makes my work look less complex. Every data analysis I deliver is fully reproducible, clearly documented, written in plain language, and backed by the methodology that actually fits your data — not the one that looks most impressive. Projects I handle regularly Dissertation data analysis — Chapter 3 through final results Panel data analysis with fixed and random effects Time series data analysis and ARIMA forecasting Survival data analysis for clinical and public health research Econometric data analysis for policy evaluation and causal inference Business data analysis for forecasting and financial modeling Healthcare data analysis for medical research and clinical trials Survey and cross-sectional data analysis for academic and applied research Have a dataset, a deadline, or a research question you're not sure how to frame? Send me a message. I respond within an hour, and I'll tell you straight away how your data analysis should be approached and whether I'm the right person to help.

99 stocks screened. 6 economies mapped. One client's manual reporting, gone overnight. I'm a Quantitative Data Analyst working in Python, R, and SQL. My background spans Mathematics, Data Science, and Industrial Engineering, three lenses most analysts pick one from. That combination means clients don't get a generic report. They get a model that actually explains what the data is doing and a decision they can act on. What I have delivered for clients: ✦ 99-stock portfolio analysis. Logistic regression, risk-adjusted, benchmarked against the Nasdaq. ✦ Black-Scholes options model integrated with decision tree analysis. Delivered on deadline. ✦ Macroeconomic analysis across 6 economies in R. Inflation, GDP, and unemployment mapped as heatmaps and time-series dashboards using Tableau. ✦ Power BI dashboard for an automotive client. 48-hour manual reporting lag, eliminated overnight. ✦ ARIMA-based forecasting model in Excel. Seasonal demand patterns detected, inventory recommendations delivered. ✦ Bank credit risk study replicated in R using panel regression and financial modeling techniques. ROA strongest predictor, R² of 0.91. What I work on: ✦ Statistical analysis and quantitative modeling ✦ Python and R for data analysis and automation ✦ Tableau and Power BI dashboards ✦ Excel models, pivot tables, and reporting automation ✦ SQL data extraction and structuring ✦ Data visualization, heatmaps, time-series, dashboards I don't just find what's broken. I use advanced mathematics and analytics to find WHY it's broken, then I build the system to fix it permanently. I work best with: ✦ Operations teams, ✦ Researchers ✦ Business owners ✦ E-commerce brand founders, ✦ Fintech managers who have data but aren't sure what it's telling them, and need one clean deliverable they can act on immediately. If your analysis is manual, your reporting takes too long, or your data sits in files nobody looks at, that's exactly where I come in. Send me a note about where your data or process is breaking down. I'll take it from there.
