About Me

Engineering with
a product mindset.

I'm Rajeev Kumar Ranjan, a Computer Science Engineering student and Full Stack Developer focused on building modern web applications.

My work sits at the intersection of engineering, product development, and experimentation. I like taking an idea, designing the system behind it, building the interface, and eventually putting the product in the hands of real users.

I'm particularly interested in full-stack development, SaaS, automation, scalable web applications, and building products that solve practical problems.
