Background
About Mantu Kumar
I’m a software engineer who enjoys building backend systems that are clean, scalable, and easy to maintain. At Rakuten, I’ve worked on projects like automating sales promotion features and improving batch processing systems, which helped improve performance and user experience. I’ve also built a full-stack DSA practice platform with real-time chat, just out of interest, to make learning and problem-solving easier for others. I’m comfortable working in diverse teams and love environments where I can take ownership, keep learning, and collaborate to solve real problems. I’m always curious, building, and looking for ways to grow.
