About

Hi, I'm Nishant—a beginner coder and tech enthusiast. I enjoy learning and working with Python, Linux, and Git. I'm also starting to explore DevOps to learn how to build, deploy, and maintain software efficiently. I use trusted resources like Harvard’s CS50P and ChatGPT to guide my learning journey. On my Hashnode page, I share simple tips and insights about coding and DevOps practices as I grow my skills each day. Join me on my journey to learn and share knowledge!
