About Me

Building the web, one layer at a time

Hey! I'm Piyush, a Computer Science undergrad from VTU Bangalore with a 9.2 CGPA and a genuine obsession with building things that scale. I thrive at the intersection of elegant frontend design and robust backend engineering.

From architecting multi-tenant SaaS platforms with RAG pipelines to crafting accessible UI component libraries — I bring both craft and engineering rigour to everything I ship.

Currently exploring the frontier of AI-native applications, real-time systems, and distributed backends. Based in Bangalore, India 🇮🇳
