Senior Solidity Contract Developer Wanted

I need an experienced Solidity engineer to take full ownership of the smart-contract layer of our platform. The core focus is green-field smart contract development: architecting, writing, testing, and deploying production-ready code that will eventually secure real value on mainnet. Because I am looking for a senior profile, I expect you to be comfortable designing upgradeable patterns, thinking through gas-cost trade-offs, and setting up a comprehensive test suite with Hardhat (or your preferred equivalent). You should also be able to propose the best approach for security—inline comments, NatSpec documentation, and integration of automated analysis tools such as Slither or MythX—well before we head to an external audit. While the initial brief is centred on development, the underlying product may evolve into a token, NFT collection, or even a small DeFi module, so versatility and a strong grasp of Ethereum standards (ERC-20, ERC-721, ERC-1155, ERC-4626) are welcome. Deliverables I will sign off on: • A fully-commented Solidity contract suite pushed to our private GitHub • Comprehensive Hardhat or Foundry tests achieving high branch and statement coverage • Deployment and verification scripts ready for testnet and mainnet • A concise technical hand-off note explaining key functions, upgrade paths, and admin controls If you thrive on writing clean, secure, and efficient Solidity—and enjoy collaborating closely over GitHub and Discord—I’d love to review your past on-chain work and discuss timelines.
