#about-me

Krishna Kumar

Hello! I am a software engineer based in Lucknow, India, specializing in building high-performance, robust, and visually stunning web applications. Bridging the gap between creative front-end design and scalable back-end architecture, I develop end-to-end systems that deliver real business value.

With expertise spanning the MERN stack (MongoDB, Express, React, Node.js) and Next.js, I focus on writing clean, maintainable code and optimizing database structures to create seamless user experiences.
