What I'm looking for

I seek roles applying ML to fraud prevention and smart-contract security in DeFi, with collaborative teams and opportunities to build scalable, compliant systems.

I am a data-driven Web3 engineer specializing in blockchain security, fraud detection, and machine learning-driven risk scoring. I build predictive models for transaction risk, integrate ML with smart contracts, and design secure API bridges between off-chain models and on-chain validation.

My work includes developing gas-efficient, security-minded smart contracts, performing automated audit testing, and delivering user-friendly DApp integrations. I combine analytical rigor with cross-team collaboration to apply AI for fraud prevention and compliance automation in decentralized finance.
