I will build interactive data visualization dashboards with d3 and chartjs

Numbers only matter if people can actually see what they mean. I build custom, interactive charts and dashboards that turn raw data a CSV, a database, or a live API into something your team or your customers can actually use, not a static export from a generic template tool.

What you get:

• Custom D3.js visualizations: line, bar, scatter, heatmaps, network graphs, geographic maps, and more
• Interactive dashboards with filtering, drill-downs, and real-time data updates
• Integration into your existing web app or SaaS product (React, Vue, or vanilla JS)
• Data cleaning and transformation before visualization, when needed
• Fully custom design not a default chart-library look

I'm a senior software engineer, so this goes beyond chart-making I can wire a visualization directly into a live data source, an internal dashboard, or a customer-facing analytics feature inside your product. If you need something a drag-and-drop BI tool can't do out of the box, that's usually where I come in.

Send me a sample of your data (or describe your data source) and what decisions the visualization needs to support, and I'll recommend the right chart types before we start.
