Frontend Leadership

Transforming Frontend Development

Senior Frontend Developer at Lajward Technologies

Led a comprehensive modernization of Lajward Technologies' frontend development practices, resulting in 8+ production applications serving 100,000+ monthly users with 60% improvement in performance metrics.

🎯 The Challenge

When I joined as Senior Frontend Developer, the company had various frontend projects using inconsistent patterns. Page load times were slow, component reuse was limited, and the development workflow was inefficient.

  • • Legacy jQuery applications mixed with React projects
  • • Average Time to Interactive (TTI) of 8+ seconds
  • • No standardized component library
  • • Inconsistent state management
The Solution

I architected a modern frontend transformation roadmap:

React Modernization

Migrated all jQuery legacy code to React with hooks-based architecture

Component Library

Built reusable component library with 50+ components reducing code duplication by 40%

Performance Optimization

Implemented code splitting, lazy loading, and bundle optimization

State Management

Standardized on Redux with best practices
