PJU//LAB

Piyush J. Utkar

full-stack + web3 + systems

lab / projects

A project index for clients who want range, sharpness, and real engineering signal fast.

This is less a gallery and more a proof board. Search by stack, category, source, or keyword and jump straight into the kind of work that matches the project in front of you.

filter logic

From Discord bots to Web3 systems to full-stack product work, the portfolio now moves as fast as the client does.

Public repositories open directly. Private repos and client builds turn into walkthrough requests, so the page never collapses into vague placeholders.

Portfolio note: this view stays focused on capability, scope, and delivery range instead of fluff.
