Gourav A.

I am a Senior Node.js Developer and React.js Developer with 15+ years of experience building scalable SaaS, eCommerce, and marketplace platforms that are designed for performance, growth, and real business impact. As a Full Stack Developer, I specialize in building high-performance backend systems using Node.js, Express.js, and API-first architecture. I design and develop secure RESTful APIs, microservices, and scalable server logic for SaaS platforms, marketplaces, and subscription portals. As a Node.js Developer, I focus heavily on backend architecture, RESTful APIs, and scalable system design. My experience in API Development includes building secure authentication systems (JWT, OAuth), payment integrations, real-time systems, and microservices-based applications. I prioritize clean architecture, performance, and long-term maintainability in every backend system I build. With strong experience as a Backend Developer, I design optimized database structures (MongoDB, PostgreSQL, MySQL) and develop high-performance server-side applications using Node.js, Express.js, and NestJS. On the frontend, I work as a React.js Developer, building modern, responsive interfaces using React.js and Next.js that integrate seamlessly with Node.js APIs and backend services.
