Summary

I'm looking for a Solidity developer with at least 1 year of professional experience building smart contracts on EVM-compatible blockchains. You should be comfortable writing secure, well-tested Solidity code and have experience using Foundry or Hardhat. Experience with DeFi, staking, NFTs, DAOs, or other Web3 applications is a plus. When applying, please tell me about your Solidity experience, the projects you've worked on, your role in those projects, and include your GitHub profile or links to deployed smart contracts if available. Please also mention your preferred development framework and briefly explain how you test and secure your smart contracts. I'm looking for someone with real production experience who can write clean, secure, and maintainable Solidity code.
