[NODE_STATUS]: Building Proovs (AI Authorization)

01. Background

I am a technical founder who has spent nine years building infrastructure where trust is the core primitive.

From zero-knowledge systems to emergency COVID response architectures, I build for environments where failure has life-threatening or systemic consequences. I specialize in the "boring" infrastructure that makes high-stakes technology possible.

Current Mission: Bridging the authorization gap in autonomous systems. I'm building Proovs to provide the cryptographic audit trails that AI agents currently lack.

02. Selected Projects

Current // 2026 — Present

Proovs

Verifiable authorization infrastructure for AI agents. An OAuth-equivalent protocol for autonomous systems enabling enterprises to cryptographically prove authorization scope and maintain immutable audit trails.

Public Sector // 2023

NFT-Based Land Registry

Digitized property records across 27,000 acres for NKDA using 500,000 NFTs on Polygon. Featured in Forbes India as a landmark case for blockchain-based public trust.

Emergency Service // 2020

COVID Authorization System

Architected system processing 500K+ movement permits during lockdowns. Maintained 99.9% uptime when failures meant delayed medical and essential services.

05. Operating Principles

Problem-First Engineering

At Airchains, I optimized for technical elegance. With Proovs, I am prioritizing 20+ enterprise validation conversations before finalizing code. Tech-first dies; problem-first survives.

Critical Infrastructure

In government systems, downtime isn't an inconvenience—it's systemic failure. I apply the same gravity to AI authorization that I applied to emergency COVID permits.
