About me
I’m Hitanshu Khandelwal, a Software Developer and B.Tech student at Delhi Technological University (Electrical Engineering, 2026). With a strong foundation in full-stack development and AI tools, I’ve built projects ranging from responsive web apps to AI-powered systems, and I currently work as a Software Development Engineer Intern at Blinkit.
Beyond coding, I’m passionate about continuous self-growth—I enjoy reading self-development books and applying those lessons in both my personal and professional life. I also train regularly at the gym, which helps me stay disciplined, focused, and energized to take on new challenges.
Looking ahead, I’m eager to leverage my skills in building impactful digital products that solve real-world problems at scale. I enjoy collaborating in fast-paced environments where I can contribute to both the technical architecture and user experience. My curiosity for emerging technologies—especially in AI-driven applications—keeps me motivated to learn, experiment, and push the boundaries of what’s possible in software development.
