In my current role, I specialize in full-stack development and performance optimization for both Web 2.0 and Web 3.0 applications, utilizing React/Next.js with TypeScript and Express/Nest.js, depending on project requirements.I work extensively with the Next.js App Router, employing Client-Side Rendering (CSR), Server-Side Rendering (SSR), and React Server Components (RSC) to build highly performant, scalable applications. Leveraging static site generation (SSG), dynamic imports, and code-splitting, I optimize for both speed and efficiency in delivering cutting-edge web experiences.My projects include developing Web 3.0 applications, particularly NFT-based platforms and marketplaces, as well as creating a React Native chat app with functionality similar to WhatsApp and Telegram. I ensure seamless integration of decentralized technologies, focusing on secure, efficient smart contract interactions.In addition to decentralized apps, I work on both Web 2.0 applications and presentation-focused websites, prioritizing performance optimization. I implement advanced techniques like memoization, critical CSS optimization, lazy loading, and dependency management to ensure fast load times and smooth user experiences. With a strong focus on Webpack optimizations and CDN integration, I deliver highly reliable and scalable solutions.

I worked on several projects for USA-based clients, focusing on building high-performance e-commerce platforms using Next.js, React, Rollup and Builder.io. My contributions spanned across four different projects, each centered on selling products online with scalable and optimized web applications.A key part of my role involved creating a custom private library of React components, which were seamlessly integrated into Builder.io CMS for drag-and-drop functionality. These components were meticulously optimized for performance and reusability, ensuring a streamlined user experience for content editors and developers alike.To guarantee high code quality and reliability, I implemented Cypress for comprehensive testing across various components and flows. Additionally, I documented the component library using Storybook, providing clear and consistent guidelines for future development and integration.This experience allowed me to deliver robust, maintainable solutions that balanced scalability with user-focused performance, tailored to the specific needs of e-commerce environments.
