I’m looking for an experienced blockchain developer to build a smart contract for a decentralized finance (DeFi) application. The platform will focus on staking and reward distribution. The main objective is to create a secure, efficient, and scalable contract that allows users to stake tokens and earn rewards over time. Key responsibilities include developing staking mechanisms, implementing reward calculations, and optimizing the contract for low gas usage. You will also handle testing, debugging, and deployment. The ideal candidate should have strong experience in smart contract development (such as Solidity) and a good understanding of DeFi staking models. Knowledge of blockchain security best practices is essential. Bonus skills include experience with Layer 2 solutions, yield optimization strategies, and familiarity with auditing tools. Please share examples of your previous work, including GitHub links or deployed contracts, along with a brief explanation of your approach to security and optimization.
