Clients come to me when the numbers have to be right. Not approximately right. Not good enough for now. Right. That standard is why businesses rely on my models for real decisions, why researchers trust me with peer-reviewed work, and why clients across healthcare, finance, marketing analytics, environmental science, and government research keep coming back. With 4+ years delivering analysis that holds up under expert review and scales across industries, one principle drives every engagement: the method always follows the problem. ________________________________________ What I Deliver ________________________________________ 📊 Statistical analysis and modelling: regression, ANOVA, hypothesis testing, EFA/CFA, SEM, cluster analysis, survival analysis, longitudinal modelling, and Bayesian hierarchical models and meta-analysis. 🤖 Data science and machine learning: predictive modelling, classification, clustering, time series forecasting, NLP, and sentiment analysis in Python and R, from raw data through to documented, deployable output. ✨Qualitative and mixed-methods research: thematic and content analysis in NVivo, ATLAS.ti, and MAXQDA; survey design, psychometric validation, and scale reliability testing. 📈 Business intelligence and analytics: Power BI and Tableau dashboards, A/B testing, financial modelling, KPI reporting, and operational analytics across corporate, government, and research settings. 🎓 Research and academic consulting: study design, sampling strategy, methodology development, results interpretation, and formatted output across healthcare, education, environmental science, social research, and doctoral projects. ------------------------------------------------------------------------------------------------------ ⚙️Tools: R, Python, SPSS, Stata, SAS, SQL, MATLAB, EViews, Minitab, Power BI, Tableau, Excel, NVivo, ATLAS.ti, MAXQDA, REDCap, Qualtrics, KoboToolbox, ODK, LaTeX, Jupyter, Git, AWS, Google Cloud, Azure. ------------------------------------------------------------------------------------------------------ ________________________________________ Where Most Analysts Fall Short ________________________________________ Most data projects fail at interpretation, not analysis. The model runs, the output is generated, and then nobody can explain what it means or what to do with it. That is the gap I close. Every deliverable includes documented methodology, transparent assumption testing, plain-language interpretation, and results structured for the audience that will use them, whether that is a business stakeholder, a doctoral committee, or a peer reviewer. I ask the questions most analysts skip, flag problems before they become expensive, and communicate clearly at every stage of the project. My Upwork record reflects this: a 100% Job Success Score, a 5.0 rating, and returning clients. Not because the work was fast or cheap, but because it was correct. ✅ Send me your project brief. I respond within 24 hours.
