About the service

I'm a Solidity developer specializing in secure smart contracts for Ethereum and other EVM-compatible networks. Over recent years I've shipped tokens, staking systems, vesting schedules, marketplaces and DAO management modules, and I treat every line of a contract as money locked inside it. I start any work with a threat model: I break down who can call what, where funds flow and how an attacker might reorder, re-enter or substitute. Only after that do I write code and try to keep it readable so auditors and your team understand the logic without guessing.

Beyond writing contracts I strengthen and audit existing ones. I perform static analysis, write comprehensive tests in Hardhat or Foundry, assess gas costs and check for classic vulnerabilities: re-entrancy, overflow issues, unchecked external calls, access control holes and unsafe upgrade schemes. I rely on proven token standards and trustworthy libraries rather than invent risky wheels, and I explicitly document all assumptions so nothing surprises you after deployment.

I also connect contracts to real applications: I build the web3 layer through which the frontend safely reads network state and sends transactions, set up event indexing and prepare deployment scripts for testnets and mainnet. If you have an idea, an unfinished protocol or a contract that needs a pair of careful eyes before launch, I'll help get it right.
