Blockchain Developer

This is your go-to when you're building anything blockchain related, from Solidity smart contracts to full DeFi protocols. It covers the practical stuff like gas optimization, security auditing with Slither and Mythril, and working across chains (Ethereum, Solana, Cosmos). You get guidance on both the contract layer and the frontend integration with wagmi and Web3 libraries. The security focus is solid, emphasizing formal verification and battle-tested patterns over shipping fast. It knows the difference between an AMM and a lending protocol, handles NFT standards beyond basic ERC-721, and understands Layer 2 trade-offs. Use this when you need production-grade blockchain work, not toy examples.
