Sumit Kesarwani

I'm Sumit Kesarwani, a Full-Stack & AI Developer with hands-on experience building production-ready web applications, AI-powered products, REST APIs, and scalable backend systems. I work across the stack using React, Next.js, TypeScript, Node.js, Express.js, MongoDB, PostgreSQL, and modern AI technologies. I've completed four internships, worked on 20+ full-stack and AI projects, and delivered 15+ client and production projects. My experience includes building secure APIs, implementing role-based access control, optimizing database performance, integrating AI features, and developing responsive user interfaces. Two results I'm proud of are improving page load times by 40% and reducing database query latency by 50% through performance optimizations. I've also contributed to open-source projects, including Apache Seata, Apache NuttX, and Open-MSS, with 15+ merged pull requests. I enjoy taking products from idea to deployment, solving challenging engineering problems, and writing clean, maintainable code. I'm also passionate about AI engineering, LLM-powered applications, and building tools that solve real-world problems. I'm looking for a remote Full Stack Developer, Software Engineer, or AI Engineer role where I can contribute to a strong engineering team, take ownership of meaningful projects, and continue growing while delivering measurable results.
