I’m Andrii, a Helsinki-based smart-contract engineer with 12 + years in software and 4 + years building production DeFi. My code currently secures multi-million TVL on Ethereum mainnet and leading L2s (Arbitrum, Base, Gnosis, Avalanche), spanning stable-value assets, isolated money-markets, BTC-backed synthetics and DEX governance contracts. By pairing a formal economics background with hands-on risk modelling, I translate financial theory into gas-efficient, audit-ready Solidity.
Concise, actionable feedback (usually < 24 h), annotated code reviews, and live white-board sessions where we turn economic assumptions into provable smart contracts. Whether you’re launching a new protocol or refining an existing one, I’ll help you build with confidence and economic rigor.
