About the service
I'm a blockchain developer who's spent the last several years living inside the Ethereum ecosystem, and I write Solidity the way it was meant to be written: carefully, with a defensive mindset, and with the understanding that real money flows through every line of code. My work covers the entire contract lifecycle — from initial architecture sketches on a whiteboard to the deploy transaction on mainnet and subsequent monitoring. I've released ERC-20 and ERC-721 tokens, staking and vesting logic, on-chain marketplaces, multisig treasuries, and off-chain backends that tie a decentralized application together, so I know where the sharp edges are before a project hits them. My approach is tests first, security first. I deliver every contract with a complete test suite in Hardhat or Foundry covering normal scenarios, edge cases, and the hostile situations auditors hunt for, and I'm happy to explain the logic behind each check. I follow the checks-effects-interactions pattern, protect against reentrancy and overflows, lean on time-tested OpenZeppelin components instead of reinventing wheels, and treat gas as a first-class concern: I measure storage layout, loops, and calldata rather than guess. When an application needs an off-chain component, I build reliable event indexers, transaction relayers, and API layers that talk to the network through ethers.js or web3.js and honestly account for finality and reorganizations. I communicate in plain language, deliver readable and documented code, and prepare contracts so a third-party audit becomes a formality rather than a rescue operation. Whether you're launching a token, building DeFi mechanics, or wiring a frontend to the network — I'll handle the smart contract side from start to finish. — Smart contracts in Solidity: ERC-20, ERC-721, ERC-1155, staking, vesting, multisig — Testing in Hardhat and Foundry with full coverage and fuzzing — Gas optimization and storage layout tuning — Security hardening: reentrancy, access control, safe arithmetic — dApp backends: event indexing, relayers, ethers.js / web3.js integration — Deployment and verification on Ethereum, Polygon, BSC, Arbitrum, and other EVM networks
