Hi, I’m Shin Sakamoto. I’m a senior blockchain engineer with over 7 years of hands-on experience delivering secure, scalable DeFi protocols and blockchain-based applications across multiple ecosystems. I specialize in Solidity and Rust, with practical expertise on Ethereum, Solana, and Polkadot, building end-to-end solutions from smart contracts to front-end interfaces and off-chain tooling.
I’m passionate about designing robust architectures, optimizing security and performance, and mentoring teammates to adopt best practices. I enjoy crafting clear, testable code, implementing automated security audits, and driving adoption of Web3 technologies through collaborative, product-focused development using tools like Web3.js, Ethers.js, and modern frameworks.
