Building with Purpose

zeroleaf - derived from "Aparna," meaning "without even a leaf" - represents building with unwavering focus and dedication.

Like Parvati's legendary penance, each project here is crafted from concept to production-ready. This portfolio demonstrates end-to-end product development: from ideation and architecture through implementation, testing, and deployment.

Every application is fully functional, thoroughly documented, and built with modern best practices.
