I will build a custom HTML js calculator or interactive dashboard tool


Level 2
À propos de ce service
Struggling to turn your spreadsheet or formula-based process into something clients or staff can use on the web without opening Excel?
I build lightweight, self-contained HTML/JavaScript tools calculators, dashboards, and KPI trackers that run in any browser, no installation needed. I've built tools like a multi-tier government salary calculator (BPS pay scale logic) and equipment-monitoring dashboards with live-updating charts, so I know how to translate real formula logic into a clean, working interface.
What you get:
- A single file or self contained HTML/JS/CSS tool, hosted or delivered ready to embed
- Your calculation logic, formulas, or lookup tables built in accurately
- Responsive design that works on mobile and desktop
- Clean, readable results with no clutter
Why work with me: I come from a data/spreadsheet background, not just front-end templates so I actually understand the logic you're trying to convert, not just the visuals.
Get started: Message me with what your calculator or dashboard needs to do, and I'll confirm scope before you order.
