About Me

Hi, I am a smart contract developer & security researcher with more than 2.5 years in Web3 with around 1.5 years focused on security research, primarily auditing DeFi protocols across multiple ecosystems. I specialize in Solidity and Rust, having audited codebases ranging from DEXs, lending protocols, and stablecoin systems to RWA tokenization and cross-chain infrastructure, and successfully reported 45+ High/Medium severity vulnerabilities.

Currently learning zero-knowledge proofs and agentic security.

Some Notable Highlights

Contest Platform Result
Lambo Win Code4rena Top 3
Ammalgam* Cantina Top 5
SukuFi Code4rena Top 10
HyperLend Cantina Top 10

* The Ammalgam finding was invalidated due to a broken test suite that prevented the PoC from executing correctly, so the result is not reflected on the leaderboard. The validity of this claim can be verified here.

Builds, Hackathons & Learning

A collection of my notable Web3 works.

Project Occasion Description
RunBro Chainlink BlockMagic and ETH Toronto Decentralized fitness marketplace rewarding users with native tokens (RBT) based on daily step counts, powered by Chainlink Functions (Google Fit API) and Chainlink Automation
TLIS Hook ETH Global Uniswap V4 hook implementing privacy-preserving batch auctions via time-locked, encrypted trading intents — prevents front-running and sandwich attacks through 5-minute batch settlement windows
0-Waste VeryChain Hackathon Blockchain-based food waste redistribution protocol on VeryChain connecting restaurants, NGOs, and couriers through a stake-to-earn mechanism with on-chain reputation and Impact NFT certificates
CertNAI Chainlink Convergence Hackathon AI-powered on-chain certification platform — Next.js frontend integrating Chainlink for verifiable credential issuance and validation
Cross-Chain Rebalancing Hook Learning Uniswap V4 hook that auto-detects arbitrage opportunities and pool imbalances, then triggers cross-chain rebalancing operations to maintain optimal liquidity efficiency
DeFi Math Challenges Learning Math problem set exploring CPAMM and CSAMM mechanics through coordinate geometry — covers invariant curves, price impact, and liquidity math
Dynamic Collateral Allocation Contest-Inspired Custom module built on top of Liquity-Bold — adds dynamic collateral reallocation strategy to the modular stablecoin codebase
