Legacy Task Management Platform Modernization
The Challenge
The client operated a Jira-like management system with:
Outdated Tech Stack: Legacy JavaScript/jQuery codebase with no type safety.
Performance Bottlenecks: UI freezes when handling large datasets (10k+ tasks/resources).
Poor Maintainability: Developers spending 30% time fixing regression bugs.
Timezone Collaboration: Distributed team across 5 timezones complicating coordination.
Consequences: Missed feature deadlines, 15% monthly user churn, and inability to compete with modern alternatives.
Our Solution
Strategic Migration
- Conducted incremental rewrite to Vue.js/TypeScript while maintaining legacy functionality.
- Implemented lazy-loading for task lists, reducing initial load time by 55% (from 4.2s to 1.9s).
Performance Optimization
- Virtualized scroll for HR allocation tables (handled 50k rows without lag).
- Web Workers for background calculations (UI responsiveness improved by 68%).
Cross-TimeZone Development
- Established overlapping "core hours" (2pm–5pm UTC) for synchronous work.
- Automated regression testing (reduced bug reports by 40% post-release).
UX Overhaul
- Redesigned 120+ components with consistent design system.
- Introduced real-time collaboration features (reduced duplicate work by 25%).
Results
✅ 3.1x Faster Rendering – Avg. task board load time dropped from 3.8s to 1.2s.
✅ Zero Data Loss – Critical HR data handling errors eliminated.
✅ 28% Faster Releases – CI/CD pipeline reduced deployment time from 45 to 32 mins.
✅ User Retention +22% – 6-month churn rate decreased from 15% to 11.7%.
✅ Maintainability Score ↑ – Code climate rating improved from C to A-.
