SHEKHAR DUBEY

I’m a Senior Frontend Engineer with 6+ years of experience building scalable, high-performance web applications using React.js, JavaScript (ES6+), TypeScript, Redux, and modern frontend architectures. I bring strong expertise in component-driven development, micro-frontend architecture, performance optimization, and reusable UI systems for enterprise applications.

At WiseTechGlobal (04/2024–Present), I architect and develop scalable frontend solutions for logistics and enterprise platforms. I integrated AI-assisted development workflows using Claude and GitHub Copilot for architecture exploration, edge-case test generation, and performance refactoring—improving feature delivery speed by approximately 30%.

I improved UI performance by 30% and reduced application load times by 40% through code splitting, lazy loading, and rendering optimization. I built real-time dashboards for contract management and shipment tracking, implemented micro-frontend architecture using Module Federation, and optimized Core Web Vitals (LCP, CLS, INP) while supporting 10,000+ row datasets via list virtualization and 80%+ test coverage with Jest, ReactTestingLibrary, and Playwright.

Previously at Blume Global (05/2021–03/2024), I designed scalable React-based frontend architectures, built reusable and maintainable UI components, and optimized API integration patterns to improve data reliability. Earlier at Wipro Limited (06/2019–05/2021), I migrated legacy frontend applications to React.js and collaborated with backend teams to integrate REST APIs and improve frontend data flow.
