About

Lead analyst at Tuyen Data. I turn disorganized data into structured, insightful reports using Excel, Power BI, and pandas—so you can spend less time cleaning and more time analyzing.

I take the stress and confusion out of working with messy data and turn it into clean, structured, and understandable information—because this is the kind of work I genuinely enjoy. Whether you're overwhelmed by inconsistent spreadsheets or struggling to build a clear dashboard, I can help.

I’m the lead analyst at Tuyen Data, a data analytics company focused on turning raw data into clarity. We provide services that are clean, accurate, and ready for immediate use—so you can stop wrestling with spreadsheets and start making informed decisions.

I specialize in data cleaning, analysis, and visualization using Excel and Power BI.

In Excel, I:

* Clean and organize raw files

* Remove duplicates, fix errors, standardize formats

* Create professional dashboards with charts, KPIs, and trends

* Automate reports and build reusable templates

In Power BI, I:

* Clean and model data for analysis

* Write complex DAX formulas for KPIs and time-based metrics

* Design interactive dashboards with slicers, filters, and drill-throughs

* Use Key Influencers and Analyze tools to find hidden insights

Typical turnaround for small jobs is 1–3 business days, depending on complexity. For larger projects, I provide clear timelines and structured delivery milestones. I also offer ongoing support, whether you need help updating reports, refining metrics, or integrating new data sources.

If you're looking for honest, structured, and reliable analytics work, backed by a business that cares about clarity—I'm ready to help.
