Project description:
"Bid only in India, I’m looking for an experienced Node.js developer to help me push several ongoing, multi-country web projects forward. The core task right now is to build out a robust data-visualisation layer. Standard charting widgets aren’t going to cut it for this use case, so I need someone comfortable creating custom visuals—whether that means fine-tuned D3.js components, WebGL interactions, or another approach you can justify.

You’ll be working on a Node.js code-base that already handles authentication, localisation, and basic APIs. Your focus will be:

• Designing and coding the visualisation modules in a way that plugs cleanly into our existing Express / TypeScript stack
• Making the front-end pieces framework-agnostic so we can surface them inside React, Vue, or even plain HTML pages used by different regional teams
• Ensuring everything is performant across varied network conditions and compliant with accessibility standards (WCAG 2.1)

I’ll supply the current repo, sample datasets, and a style guide. I’d like an MVP of the custom visualisations, full unit tests, and concise setup instructions as the initial milestone, followed by iterations based on stakeholder feedback from each market.

If you’ve built distinctive visual layers on top of Node.js back-ends before, please share a short demo link or repo snippet that shows off your best work, along with a quick outline of the libraries you’d lean on here." (client-provided description)
