Solidity / Smart Contract developer with 4 years of hands-on experience building DeFi systems on EVM chains (Base, Arbitrum, Polygon, Ethereum).

I write smart contracts from scratch and take them all the way to deployed-and-verified on mainnet. My work includes:

- Aave V3 liquidation bot with flash-swap funding and multi-DEX routing (Uniswap V3 + Aerodrome)
- Atomic flash-loan arbitrage across two DEXs
- Synthetix-style staking (rewardPerToken pattern)
- ERC-20 and ERC-721 tokens implemented from scratch
- Multi-token payment contracts with safe transfers for non-standard tokens like USDT
- Real-time risk monitoring tooling for the Morpho lending protocol

I care about the security details that matter when contracts handle real funds: reentrancy mitigation, safe ERC-20 transfers, access control, and simulating transactions before execution.

I work independently and ship fast. I'm looking for remote smart-contract development work — full-time, contract, or bounties. Open to payment in crypto (USDC/ETH) or traditional methods.

All my code is open-source and deployed on-chain: github.com/alexpetrache-dev
