Need a dashboard that holds up when someone actually questions the numbers, or a research figure clean enough to go straight into a journal submission? I build both. Most BI freelancers stop at connecting a dashboard to whatever data already exists. I work a step upstream. I scrape and clean the raw data in Python or R first, then build the dashboard or figure on top of it, so what you're presenting is actually correct, not just pretty. Power BI: DAX measures, Power Query, clean data models. Tableau: Calculated fields, dashboards built for non-technical stakeholders to actually use. Python & R: EDA statistical charts, publication-quality figures (box plots, heatmaps, multi-panel layouts) formatted to journal specs. Data Collection: Python web scraping and cleaning pipelines that feed straight into the above, so you're not manually pasting numbers into Excel. 5.0-rated across my completed Upwork contracts, including a full figure rebuild for a published research paper and comparison dashboards for a technical report client. I do the work myself. No subcontracting, no handoffs. Tell me what the dashboard or paper needs to show, and I'll reply with a clear next step within a day.
