About this Gig

I write Solidity smart contracts that are tested properly before they go anywhere near mainnet.


Some of what I've built:

  • An ERC-1155 NFT minting and marketplace system, rewritten as upgradeable (UUPS) contracts with role-based access and 100% test coverage
  • A Polymarket-style prediction market on BNB Smart Chain
  • On-chain lottery and wheel-of-fortune games using the Diamond pattern (EIP-2535) and Chainlink VRF for fair randomness
  • Token presale, sacrifice and DEX arbitrage contracts


I also do security reviews, and I reproduce the issues I find with proof-of-concept exploits so you can see the problem for yourself.


What I can do for you:

  • ERC-20, ERC-721 and ERC-1155 tokens
  • Presales, staking, vesting and marketplaces
  • Upgradeable contracts (UUPS, Diamond)
  • Chainlink VRF and oracle integration
  • Testing with Hardhat or Foundry
  • Deployment and verification on Ethereum, Polygon, BNB Chain, Base and PulseChain


You'll get clean, commented code, a full test suite and clear notes on how everything works.
