About this gig

Need a dashboard that is actually useful, not just pretty?

I will turn your CSV, Excel, or structured dataset into a clean and interactive Streamlit dashboard in Python.


You will get a dashboard where you can quickly explore your data, track KPIs, compare trends, filter results, and understand what is really happening without digging through spreadsheets.


I can build:

  • KPI cards and summary metrics
  • interactive charts with Plotly
  • filters, dropdowns, and date selectors
  • time series, comparisons, and performance views
  • cleaned and prepared data
  • multi-page Streamlit dashboards
  • clear business-focused insights


I work with Python, Pandas, NumPy, Plotly, and Streamlit.


I have built real analytics dashboards, including a tennis price-feed latency project with more than 140,000 matched market events, where I compared two platforms and analyzed which one delivered market prices faster.


Send me your dataset and tell me what you want to understand or track. I will turn it into a dashboard that is clear, practical, and easy to use.


For complex projects or multiple data sources, please message me before ordering.
