Challenge
The client operated a Jira-like management system with a legacy stack that was crushing both performance and developer velocity.
- 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% of time fixing regression bugs
- Timezone collaboration - distributed team across 5 timezones complicating coordination
- Missed feature deadlines, 15% monthly user churn, and inability to compete with modern alternatives
Business Goals
- Modernize the stack to Vue.js + TypeScript without halting feature delivery
- Make the UI responsive at enterprise data volumes (10k+ tasks)
- Cut regression bug volume through type safety and automation
- Coordinate effectively across a 5-timezone team
- Reduce churn and re-establish parity with modern competitors
Solution
01 Strategic migration:
- Conducted incremental rewrite to Vue.js/TypeScript while maintaining legacy functionality
- Lazy-loading for task lists, reducing initial load time by 55% (from 4.2s to 1.9s)
02 Performance optimization:
- Virtualized scroll for HR allocation tables (handled 50k rows without lag)
- Web Workers for background calculations (UI responsiveness improved by 68%)
03 Cross-timezone development:
- Established overlapping core hours (2pm–5pm UTC) for synchronous work
- Automated regression testing (reduced bug reports by 40% post-release)
04 UX overhaul:
- Redesigned 120+ components with a consistent design system
- Real-time collaboration features (reduced duplicate work by 25%)
How the Solution Works
Legacy and modern code coexist during the migration: each screen is rewritten in Vue.js/TypeScript and dropped into the existing shell, so users see continuous improvements without a big-bang release. Heavy-data screens use virtualized scroll and Web Workers to keep the main thread responsive at 50k+ rows, and a shared design system keeps the rewritten components visually and behaviorally consistent.
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 improved from C to A-
