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.
