Always a builder at heart — full of caffein

Building Sage — a co-pilot for every crypto move

2026

Built Sage on Solana

A personal AI co-signer for Solana wallets, built on Squads Protocol and submitted to the Colosseum Frontier hackathon. Live on Solana mainnet from day one — no testnet hand-wringing.

Built Zhentan — BNB Hackathon winner

Won top project at the BNB OpenClaw Hackathon out of 600 builders. The community spun up a $ZHENTAN token within hours; it hit a $250k market cap and crossed 150 users in week one. Felt good.

Presented agentic payments at Devconnect Argentina

Nominated by the EF ERC-4337 team to present an agentic payments vision — x402 on smart accounts with delegated access. Buenos Aires in November is a kind of magic.

Launched Brewit

Led the team to build agentic crypto account infrastructure for individuals and teams, powered by Safe. Claude desktop integration, ~5k users, $1.5M in volume, $200k AUM. Still my favourite thing we've shipped.

Finalist at ETHIndia 2024

Two sleepless nights in Bengaluru, one stubborn idea, a very good team. Made it to the final stage.

Smart account delegation at AA Hub Devcon

Demoed delegated access for automation on ERC-4337 smart accounts in front of Vitalik Buterin at AA Hub Devcon Bangkok. Tried not to think about who was in the room.

Received the OBRA Grant from Safe

A grant from Safe to build developer tools for the Module Marketplace on Safe smart accounts. The kind of support that changes a year.

2023

Finalist at ETHIndia 2023

Year one of many. The hallway was the best part.

ZenGuard — the Safe Module Marketplace

Kept building ZenGuard as a module marketplace for Safe smart accounts. A second grant from Safe followed.

Built ZenGuard — won the AA hackathon

Built ZenGuard and won the Account Abstraction hackathon — a modular authorization layer and marketplace for Safe smart-account plugins. The thread that pulled the next two years.

2021

Built Safient

Co-founded Consenso Labs and built Safient — a non-custodial way to recover and inherit crypto assets using MPC. Passionate team, real problem, the early days of smart-wallet UX.

2019

Founded Consenso Labs

Started a Web3 research and development lab focused on blockchain infrastructure and smart-account tooling. Mostly: a quiet bet that this would matter.

Blockchain Faculty — Amity Online

Part-time faculty for the PGD-BTM blockchain programme at Amity Online. Teaching the thing while learning the thing.

2018

Authored “Foundations of Blockchain”

One of the earliest developer books in crypto, published by Packt. A year of writing discipline after quitting a full-time job to chase this.

2017

Senior Developer — CoWrks

Full-stack developer with managerial responsibilities. Led design and build of an internal network-enhancement project.

2016

Software Engineer — RSA Security

Worked on RSA's flagship network and log analytics tool, Security Analytics. Deployment and operations strategy during active development.

2015

Intern — RSA Security

First professional experience in information security at one of the most respected names in the field.

2014

MTech — Computer & Information Systems Security

Master of Technology from Manipal Institute of Technology, specialising in Information Assurance and Systems Security. The foundation of everything built since.

A little more

I have been building in crypto since 2018. Before that, I spent years inside information security — first as an intern, then a software engineer at RSA — which is where I learned to love hard problems and paranoid systems thinking. In 2019 I founded Consenso Labs, a small R&D lab for blockchain infrastructure and smart-account tooling. Since then I have shipped Safient, ZenGuard, Brewit, Zhentan, and most recently Sage — a personal AI co-signer for Solana wallets, live on mainnet from day one. Along the way: a developer book with Packt, two grants from Safe, two ETHIndia finals, talks at Devcon and Devconnect, and one really loud hackathon win at BNB OpenClaw. If you are working on smart accounts, agentic crypto, or the uncomfortable middle ground between AI and on-chain identity — say hi.
