Who I Am

About Me

I'm Ayush Kumar, a Computer Science graduate from Chandigarh University, currently working as an Assistant System Engineer at TCS. I engineer frontend systems for the Passport Seva Project — a mission-critical government platform serving the Ministry of External Affairs.

My journey into software began with curiosity and evolved through solving 1491+ algorithmic problems, contributing to IEEE-published research, and building full-stack products from the ground up. I specialize in the MERN stack and have deep expertise in Java, Spring Boot, and microservices architecture.

When I'm not building software, you'll find me exploring new open-source tools, contributing to the dev community, or enjoying the serenity of my hometown Haridwar.
