About

Hi! I am Arnav Khajuria, a software developer with 1+ years of experience in frontend, backend, and DevOps. I hold a B.E. in Electronics & Communication Engineering from Government College of Engineering and Technology, J&K, India. My journey into tech began with a childhood fascination for computers and software. Over the years, I’ve explored a wide range of programming languages, frameworks, and technologies through self-learning and real-world projects. Today, I work as a full-stack developer with solid experience in building scalable web applications and managing cloud infrastructure and CI/CD pipelines. I also have a growing interest in blockchain development and enjoy creating secure, innovative solutions that leverage modern technology. Additionally, I am deeply interested in the field of Artificial Intelligence and am actively pursuing it to expand my skills and apply AI in real-world applications. Outside of tech, I’m a gamer and a musician.
