I will build a simple browser based calculator or data tool
Jeff
About this gig
Need a small browser-based tool for a clearly defined task?
I can build a focused calculator, form-based utility, or simple CSV/text conversion page using HTML, CSS, and JavaScript. You receive a lightweight client-side tool, source files, and brief usage instructions for the agreed browser and use case.
Please contact me before ordering with your calculation rules or workflow, sample inputs, expected outputs, and preferred layout. We will agree on the features, supported browsers, and scope first.
Basic covers one calculation with up to five inputs. Standard covers up to three related operations. Premium covers one client-side CSV or text tool with agreed processing and local file input/output.
User accounts, databases, payments, backend services, API integrations, native mobile apps, WeChat mini-programs, hosting, domains, and ongoing maintenance are not included. Hosting and deployment require separate discussion. Any paid services require your approval.
