Senior Full Stack Developer

Hi,
 With 8+ years of experience in blockchain and full-stack development, I specialize in building secure, scalable, and gas-optimized smart contracts for DeFi applications.
✔️ DeFi & DEX Expertise: Co-developed TiFi Bank with PancakeSwap, a DEX with 20,000+ active users.
✔️ Gas Optimization & Security: Implemented custom smart contract optimizations that reduced gas fees by X% and improved security.
✔️ Full-Stack Web3 Integration: Built staking, farming, and liquidity pools with React, Next.js, and Solidity.
✔️ Security Best Practices: Audited and protected smart contracts from reentrancy, flash loan attacks, and oracle manipulation.
✔️ Develop & audit smart contracts (staking, lending, liquidity pools, NFT minting, etc.).
✔️ Optimize transaction costs with Solidity best practices.
✔️ Integrate Web3 with a seamless user experience (React, Next.js, WalletConnect, Metamask).
✔️ Ensure contract security & compliance with thorough audits.
Past Work: I recently built a staking & farming platform that handled $X million in TVL, improving efficiency by 25%.
Would you be open to a quick chat to discuss how we can scale your project efficiently? Looking forward to working together!
Best,
Strong Blue.
