Pseudonymous Web3 developer — smart contracts (Solidity + Solana/Anchor), Next.js dApps, and on-chain tooling. After years of confidential, NDA-bound client work, I'm now building in the open. I ship production-grade Web3 software: audit-ready contracts with full Foundry test, fuzz and invariant coverage; Next.js/React frontends (wagmi/viem, RainbowKit); and on-chain automation. I work test-first — every contract ships with a complete test suite and a clear README, so you can verify the work before you pay. Clean, documented code, fast turnaround, escrow-only. Stack: Solidity, Foundry, Rust/Anchor (Solana), TypeScript, Next.js, wagmi/viem, ethers/web3.js, The Graph/Ponder — multichain across EVM (Ethereum, Base, Arbitrum, Polygon, BSC) and Solana.

Job title

Web3 Developer — Solidity + dApps

Work experience & achievements

Several years of pseudonymous, client-confidential web3 work across DeFi, token systems, and on-chain tooling. Smart-contract development in Solidity/Foundry and Solana/Anchor (test-first), plus dApp frontends in Next.js with wagmi/viem. Multichain: EVM (Ethereum, Base, Arbitrum, Polygon, BSC) and Solana (Rust/Anchor). All engagements were private/under NDA — which is exactly why I'm now building a public, verifiable record.

Work experience & achievements

Most of my past work is private or under NDA and can't be shown publicly — but rather than ask to take my word for it, I'm building a fully open, verifiable track record from scratch - so my work can be judged directly.
