Blockchain Engineer building at the AI × DeFi intersection | DEX & Perpetuals Infrastructure | MSc CS (AI) @ University of Sydney

About

Blockchain engineer with 5 years of experience designing and shipping production DeFi trading systems — perpetual exchanges, concentrated liquidity AMMs, order books, and token launchpads — across EVM, Solana, and SVM ecosystems. Currently pursuing a Master of Computer Science at the University of Sydney, specialising in Artificial Intelligence, to bridge my deep DeFi infrastructure expertise with machine learning and intelligent systems. Most recently, I built Valiant — the flagship DEX on Fogo — delivering CEX-speed spot trading, perpetual futures, and token swaps to $1.5M TVL at launch. Previously, I developed perpetual exchange smart contracts and risk systems at Lexer Market on Arbitrum, and built full-stack DApps and upgradable contract architectures at SW7 Ventures. I'm focused on the convergence of AI and DeFi: autonomous trading agents, ML-driven liquidity management, intelligent on-chain execution, and LLM-powered interfaces for decentralised finance. I believe the next generation of DeFi protocols will be built by engineers who understand both smart contract infrastructure and machine learning — and that's the intersection I'm building at. Open to roles at the intersection of AI and DeFi. Let's connect.
