Bootstrap/UI Developer for Web Application Modernization

We are looking for an experienced Bootstrap/UI frontend developer to modernize and refresh 3 existing web application pages within our proprietary customer intelligence platform.

This is NOT a full rebuild.
The backend, APIs, calculations, and widgets already exist and are functioning.

The project is focused on:

* Bootstrap-based UI modernization
* improved layout/spacing/alignment
* professional executive-dashboard styling
* responsive cleanup
* visual consistency
* improved presentation of existing widgets/charts/tables

Current pages are functional but visually dated and require a cleaner, more modern executive dashboard appearance.

IMPORTANT:
You will NOT be redesigning business logic or rebuilding the application architecture.
This is primarily:

* frontend facelift
* Bootstrap modernization
* CSS/layout refinement
* improved UX/UI presentation

Current UI pages attached.

1. Executive Summary Dashboard
2. GAP 2.0 – Experience Drivers View
3. GAP 2.0 – Detractor Intelligence View

Current pages already contain:

* charts
* word clouds
* tables
* KPI widgets
* filters
* navigation panels

We want these visually elevated into a cleaner SaaS-style executive interface while preserving existing functionality.

Skills Required:

* Strong Bootstrap experience (Bootstrap 4/5 preferred)
* Responsive UI/UX design
* HTML/CSS/JavaScript
* Dashboard-style frontend development
* Experience modernizing legacy interfaces
* Strong eye for spacing, typography, visual hierarchy, and executive-level presentation

Nice to Have:

* Experience with analytics dashboards
* Experience with data visualization layouts
* Experience improving enterprise SaaS interfaces
* Ability to suggest modern layout improvements

Deliverables:

* Updated frontend for 3 pages
* Modernized Bootstrap styling/layout
* Mobile/tablet responsive improvements
* Clean professional executive appearance
* Organized/commented frontend code

Please provide:

* Examples of Bootstrap dashboard work
* Screenshots/portfolio links
* Experience modernizing older systems
* Estimated timeline
* Estimated fixed-price quote

This is likely the first phase of additional UI modernization work as the platform evolves.
