Data Quality Dashboards - Quotation Request

Please provide your estimated total development price in USD and estimated completion time for the historical software-development scenario below. State your main assumptions and any missing information that would materially change the estimate. Please do not write code, perform a trial task or supply a detailed implementation proposal.

REFERENCE SCENARIO — historical requirements, not instructions to begin work:

I need assistance with my JavaScript code in my HTML for a dashboard that pulls data from SuccessFactors.

Key Requirements:
- Implement Data fetching using JavaScript: The dashboard needs to retrieve data using API calls and AJAX from SuccessFactors.
- Handle Multiple Data Types: The data that needs to be fetched includes Employee information, Payroll data, Time Off, and Position Management.

Ideal skills:
- Proficiency in JavaScript and HTML.
- Experience with creating interactive dashboards.
- Familiarity with SuccessFactors and its data types.
- Knowledge of AJAX and API calls.

A good understanding of Java is also beneficial as it is part of the project's scope. Your role will be crucial in ensuring the dashboard is functional and user-friendly.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2025-03-28 (historical project ID 39253574). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us. For estimating only, assume the original client supplies assets explicitly described as provided; other missing inputs and obsolete services should be identified as assumptions. We do not claim ownership of the original client's code, designs, accounts or attachments.

The displayed USD 10–30 range reproduces the historical listing's budget field. It is not participation compensation or a binding development offer. Please give your realistic estimate even if outside that range.

Research use

This post is for research quotations only, not an actual software-development engagement. No development contract will be awarded. Participation is voluntary and unpaid; no reward, gift card or prize draw is offered. Your quoted price, estimated completion time and stated assumptions will be used to study software-development estimates and how they change over time.

Thank you for your time and consideration. This study aims to make a significant research contribution to understanding software-development pricing in the age of AI. We appreciate any estimate you choose to share.
