Smart contract development with solidity. ● Development and support of complex system of various smart contracts with different logic(NDA) ● Polygon mainnet, Ethereum mainnet ● Integration and usage of Oracles, and DEX, such as Algebra finance ● Upgradable contracts, proxy pattern, EIP-1967 ● Unit tests, fork tests, debugging, test coverage, internal analysis and audit ● Various code optimizations such as decreasing gas usage. ● Refactoring, comments and docs ● Work with external audits, such as providing docs and instructions about logic and scope, and work with audit reports afterwards. ● Team work, participation in team calls, discussions about best solutions for current tasks, and setting deadlines ● Work and interaction with frontend developers, assisting in connecting smart contracts to the frontend side

Crossledger continuous ICO contracts.

Freelance smart contract development.

https://github.com/ZooDAO-Project Research and development in DeFi, GameFI, and NFT. Creating from scratch complex system of smart contracts in Defi\GameFI field, With funds deposit management and transfer into vaults for profit, and game mechanics with NFT. Median TVL over 500k$ Work and integrations with various projects such as: - Uniswap V2-V3, - ChainLink, - Curve (including VeCRV), - Balancer (including VeBal), - Aragon, - LayerZero. Interactions with vaults such as Yearn v2 vaults or Moonwell pools, with interfaces or ERC4626 standard. Build different smart contracts, such as: - Staking pools for ERC20 and ERC721, - Yield farming, - Lottery contracts, - Nft contracts. And implementation of various game mechanics into smart contracts and NFT. Successfully ran an ICO and crowdsales with smart contracts. With timelocks and customisation of funds unlock logics and other various requirements. Created a lot of different unit tests, as well as integration tests, and more complex custom tests for testing game logics and test coverage. - Truffle Jaca script, - Hardhat, Java script, Type script, - Brownie, Python. Made a lot of code optimizations in smart contracts, especially to decrease bytecode size or gas usage. Ethereum Mainnet, Moonbeam, Arbitrum networks.

Unit tests with JS and truffle, refactoring, docs.

Took part in ICO and crowdsales, Research and analysis of different projects, Docs, code refactoring, unit tests(brownie).
