Experienced Solidity Developer Needed

I'm looking for an experienced Solidity developer to build production-quality smart contracts for an EVM-compatible blockchain application.

This is a project-based freelance engagement with clearly defined deliverables.

The selected developer will be responsible for:
- Designing and implementing secure Solidity smart contracts.
- Writing comprehensive unit and integration tests using Foundry or Hardhat.
- Optimizing contracts for gas efficiency where appropriate.
- Preparing the project and documentation required for an independent third-party security audit.
- Resolving issues identified during the audit process.
- Assisting with the integration of the smart contracts into an existing application.
- Following secure development and testing best practices throughout the project.

Required Experience
- 3+ years of professional Solidity development experience.
- Experience building production smart contracts deployed on EVM-compatible networks.
- Strong knowledge of Solidity, Foundry or Hardhat, OpenZeppelin, and Ethers.js.
- Experience preparing projects for external security audits.
- Solid understanding of common smart contract security best practices.
- Experience using Git and collaborative development workflows.

Nice to Have
- Experience with complex smart contract systems.
- Previous experience addressing findings from independent security audits.
- Strong gas optimization skills.
- Experience integrating smart contracts with frontend or backend applications.

If this project matches your experience, I'd be happy to hear from you. Please include a brief introduction about your background, examples of relevant Solidity projects you've worked on, and any GitHub or portfolio links that demonstrate your experience. If you've worked on contracts that have undergone independent security audits or have been deployed to production, feel free to mention those as well.

I look forward to reviewing your application.
