Challenge
A high-traffic commercial web platform with thousands of daily active users was suffering from performance degradation and high technical debt. The legacy codebase (pure JavaScript) slowed down feature onboarding, while a lack of automated deployment led to frequent manual errors.
Actions Taken
- Analyzed and refactored heavy React components, optimizing rendering cycles and data caching via React Query.
- Successfully migrated the entire large-scale application from JavaScript to TypeScript for type safety and maintainability.
- Built a centralized, reusable UI component library from scratch, accelerating feature delivery across the team.
- Engineered automated deployment workflows using GitHub Actions to eliminate manual intervention.
Results
- Reduced initial page load time by over 30%, drastically improving core web vitals.
- Slashed deployment time and post-release errors through automated CI/CD integration.
- Accelerated time-to-market for new features via the internal UI library.
