   Responsive and accessible web designs were implemented in Angular 17 using Material Design and Bootstrap, enhancing UI aesthetics and usability.•Developed dynamic and reusable UI components using React 18, improving application performance and user experience by leveraging the Virtual DOM and React Hooks.• Developed scalable backend applications using Node.js leveraging its non-blocking event-driven architecture to handle high-concurrency workloads efficiently.• Ensured each Micro Frontend maintained its own state using NgRx or local services, preventing cross-app state pollution while allowing controlled state sharing through event-driven architecture.• Managed asynchronous data streams efficiently using RxJS in Angular applications ensuring seamless event handling, API calls, and user interactions• Implemented GraphQL to optimize data retrieval by fetching only required fields reducing payload size and improving performance for mobile applications with limited bandwidth• Developed complex logic using JavaScript closures, currying, and higher-order functions, improving modularity and reusability.• Ensured backward compatibility and gradual adoption of TypeScript in legacy JavaScript projects, migrating modules incrementally while preserving functionality.• Optimized web performance by minimizing HTML5 DOM reflows and repaints reducing page load times and improving rendering speed for complex layouts and UI-heavy applications• Used CSS3 pseudo-classes and pseudo-elements to enhance UI interactions adding dynamic styles to elements like buttons forms and navigation menus without extra markup• Migrated state management from Angular services to NgRx improving scalability, reusability, and making state changes more traceable
