Bittu Kumar

My name is Bittu Kumar, and I am a full-stack developer with over three years of experience in web development. I have in-depth understand and knowledge of both the frontend and backend of web applications. My major skills includes JavaScript, TypeScript, React, Next.js, Node.js, Python, and various other web development tools and languages.

Additionally, I specialize in 3D web development primarily using Three.js, WebGL and Blender 3D, which enables me to create 3D models, visualizations, and other eye catching visuals for websites.

I have experience in building end-to-end products and mentoring junior developers, reviewing their work, and ensuring overall team productivity. I enjoy solving real-world problems and am always eager to learn and grow in different fields.

I am excited about the possibility of contributing to your projects.
