About Me
Haan Ji, I’m Manoj Kumar, a Full Stack Generative AI & DevOps Engineer passionate about building modern web applications, SaaS tools, and AI-driven solutions. My expertise spans Node.js, Next.js, React, React Native, MongoDB, PostgreSQL, Docker, and AWS, with hands-on experience in LLMs, RAG systems, LangChain, Vector Databases, and Prompt Engineering. I’ve built and deployed 20+ full-stack projects, including AI-powered tools, image compressors, real-time chat apps, and admin dashboards. Some are live SaaS products, while others support client businesses such as Utopia Technology and Ariston Instruments. Beyond full-stack development, I enjoy working on DevOps & cloud infrastructure setting up CI/CD pipelines, containerizing applications with Docker & NGINX, and deploying scalable systems on AWS. I also love sharpening my skills in backend architecture, system design, and cloud deployments. Outside of coding, I share developer insights, explore new APIs, and tackle challenges on LeetCode (400+ problems solved) to stay sharp. Open to opportunities in AI SaaS development, Generative AI projects, and scalable web apps. Let’s connect!
