Kalpana Chavhan

Full Stack MERN & Next.js Developer · AI/ML Explorer · DSA Enthusiast

About Me

BCA graduate who found her calling at the intersection of design and engineering. I build full-stack applications that are clean on the outside and solid on the inside.

Currently deep-diving into system design, advanced DSA, and machine learning optimization. When I'm not coding, I'm exploring open-source, sketching, discovering obscure music artists, or falling down a psychological horror rabbit hole at midnight.
