Hello! I have an experience in smart contract development. Skills: I worked with standard smart-contracts(ERC20, ERC223), crowdsale smart-contracts, some special smart-contracts. On development, I'm working with Truffle, Solc, Open Zeppelin framework, Oyente analysis tool, Web3 library, NodeJS. I'm writing SC tests. I also check my smart contracts on vulnerabilities: reentrancy attack, over and underflows, replay attack, reordering attack, short address attack. Projects: My current project is Ethereum Payment Channel Project Description: Fast Ethereum blockchain payments without worrying about block confirmation times. Security is enforced by Ethereum smart-contracts without creating an on-blockchain transaction for individual payments. Payment speed measured in milliseconds to seconds. Technologies: Web3, Solidity, Truffle, NodeJS API Web/Mobile Ethereum & Bitcoin wallet with “stacking” smart contract Project Description: Create/import BTC & ETH & Tokens wallets, send/receive transactions. Integration with smart contracts. Smart-contract for stacking coins. A user can "stack" coins for some period of time 6 months/year/2 years and receive every month profit to his address. At the end of a chosen period user will get his "stacked" coins back. Technologies: JavaScript/TypeScript, Web3, Solidity, Truffle, Angular 6, Ionic You can examine some projects in my portfolio. I'd like to start working with you. Thank you in advance!
