Do you need someone who can handle your entire data journey? From collecting data, to analysing it, to automating the processes around it, and finally presenting it in a stunning, interactive dashboard? You've found that person.
I'm Catherine, a data analyst and statistician with deep expertise across the full data pipeline. I don't just run numbers. I help you collect, clean, analyse, automate, and visualise your data in a way that drives real decisions.
What I bring to your project:
📊 Statistical analysis & research: Hypothesis testing, regression, SEM, survival analysis, psychometrics/scale validation, and econometric modelling using SPSS, R, Stata, Python, Jamovi, and JMP. I've contributed to peer-reviewed journal publications through my statistical work on surgical databases (NSQIP).
🔍 Qualitative research: Thematic and content analysis using NVivo, MAXQDA, and Atlas.ti for interviews, focus groups, and open-ended survey data.
⚙️ Automation & workflow design: I build end-to-end automated pipelines using Make and Google Apps Script, including integrations with Stripe, Google Forms, Google Sheets, landing pages, and more. Recent clients have seen their manual data workflows fully automated.
📈 Dashboards & data visualisation: Interactive executive dashboards in Power BI and Looker Studio, tailored for marketing teams, operations, healthcare, and finance. I turn raw data into clear, compelling visual stories.
📋 Survey design & data collection: End-to-end survey projects using Google Forms, Typeform, and Qualtrics, including automated data pipelines from form submission to clean, analysis-ready datasets.
I've worked across yachting, healthcare, finance, and academia, and I also offer tutoring in SPSS, R, and Stata for students and professionals. Let's talk about how I can support your project.
