Web VFD Speed Trend Dashboard
Budget: ₹1,500 – ₹12,500 INR
I need a web-based dashboard that visualises the speed of our Variable Frequency Drives in real time and lets me scroll back through historical data for quick analysis. The data stream is already available over a simple HTTP/JSON endpoint; what I’m missing is a clean front-end that updates live, plots past values, and feels snappy on any modern browser.
You are free to choose the framework you are most comfortable with—React, Angular, Vue.js or another—as long as the result is lightweight, responsive, and easy for me to maintain.
Deliverables
• A single-page dashboard served from a small Node/Express or comparable back-end.
• Real-time speed widget that refreshes automatically without page reloads.
• Interactive trend chart with pan / zoom and custom date-range selection.
• Clear build/run instructions plus commented source code stored in my Git repository.
Acceptance criteria
• Live speed updates appear within two seconds of a change.
• Historical view loads at least one week of data in under three seconds.
• Works on Chrome, Edge, and Firefox latest versions without extra plugins.
