About

Protocol-focused blockchain engineer specializing in DeFi integrations and developer education. I build production systems from smart contracts to full-stack applications, and translate complex protocols into content developers actually use.

Currently: Blockchain Engineer at DeFiConnectCredit Production DeFi integration (Aave v3, Uniswap v3/v4, Curve, GMX). Security reviews, testing infrastructure, gas optimization.

Background: Uniswap Hook Incubator (UHI7) Graduate | School of Solana Student | Core Protocol Engineer at TruthBounty

Featured Projects

Sentinel AI-Powered Smart Contract Auditor

Multi-Agent Security Framework | Solidity, Rust, Move, Cairo

Automated auditing framework for competitive security contests (Sherlock, Code4rena, Cantina). Multi-agent pipeline: reconnaissance, static analysis (Slither/Mythril), LLM-powered vulnerability hunting, and Foundry-based PoC generation with mainnet fork validation. Detects oracle manipulation, flash loan attacks, reentrancy variants, and access control issues across 4 smart contract languages.
