Michael Krisna Cahyadi

I’m a Full-stack Web3 developer with 4+ years building production-grade DeFi protocols, NFT platforms, and crypto payment solutions across Ethereum, Berachain, BNB Chain, and Solana. I specialize in Solidity smart contracts (Foundry, Hardhat, OpenZeppelin), wallet integration (WalletConnect, MetaMask, Coinbase), and React/Next.js frontends with Wagmi/viem, with a strong focus on upgradeability, gas optimization, MEV protection, and role-based access control.

In my current Senior Full-Stack Web3 Engineer role, I lead full-stack Web3 engineering across multiple products—owning architecture decisions, code reviews, and CI/CD pipelines (Vercel, GitHub Actions, Docker). I’ve shipped real-time multiplayer infrastructure with Node.js/Express, Socket.io, and Prisma/PostgreSQL, and I’ve built and maintained Go backend services for REST APIs, event indexing, and background jobs—backed by infrastructure automation with Pulumi and Cloudflare and deployment on Google Kubernetes Engine. I’m also actively involved in the web3 community and have spoken on blockchain security and decentralized product architecture.
