At a Glance
Client
B2B Analytics Company
Challenge
Legacy jQuery dashboard with 4-6 second load times, poor mobile experience, and increasing support tickets
Solution
Incremental migration to modern React application with optimized data fetching
Results
- •Page loads under 2 seconds
- •Reduced support tickets
- •Mobile-responsive dashboard
- •Faster feature development
The Problem
A B2B analytics company had a dashboard built in 2018 using jQuery and server-rendered templates. As their user base grew, the limitations became painful:
- Slow page loads (4-6 seconds)
- Poor mobile experience
- Difficult to add new features
- Increasing support tickets about UI issues
They needed a modern rebuild without disrupting their existing users.
What We Did
We took an incremental migration approach over 12 weeks:
Audited existing codebase, interviewed power users about pain points, and designed component architecture.
Built component library with Tailwind CSS, implemented authentication and state management, created API layer.
Rebuilt chart and visualization components, implemented saved views and user preferences, created mobile layouts.
Set up feature flags for gradual rollout, migrated users in stages (10% → 50% → 100%), monitored for issues.
The new dashboard was built with React, TypeScript, and TanStack Query for efficient data fetching. We added lazy loading for heavy components and smart caching to reduce API calls.
The Outcome
Page Load Time
< 2 sec
Down from 4-6 seconds
Support Tickets
Reduced
Dashboard-related issues decreased
Mobile Usage
Increased
Dashboard now usable on phones
The client was able to deprecate their legacy code and focus maintenance efforts on a single, modern application. The team can now ship new features faster with the modern codebase.
Client Feedback
