Background

About Marco Negroni

I build production Web3 and industrial.NET systems, end-to-end. At dOrg, I led parts of Zenchain (EVM-compatible Bitcoin L1)—shipping ZenBridge (BTC↔EVM bridge), Zentrace (explorer), ZenEarn (staking/launchpad), and a Safe App with wallet integrations. I created ZenQuest (1M+ users), a quest-based onboarding & rewards platform with verifiers, anti-bot protections, reward distribution, and analytics. I also contributed Zenchain node E2E tests across consensus, RPC, mempool, and events (CI-backed). I’ve delivered dApps and infra including PrivateDAO, DAO Drops (retroactive public goods funding with PairDrop pairwise voting), FayreMarketplace, GenieMint (AI-assisted minting), and a Safe (formerly Gnosis Safe) module for governed swaps. Before/alongside Web3, I built a portfolio of manufacturing applications & systems: geometry search (MAUI), custom AI model + inference APIs (PyTorch Lightning) for process optimization, inventory management handling multi-million-euro steel flows, real-time production planning (WIP, scheduling, ETA forecasts), and cross-functional tools for operations, sales, and customer support (orders/quoting, customer portals, case tracking). Tech I use: Solidity, Hardhat, Viem/Ethers; wallet integrations (MetaMask, WalletConnect v2, Safe Apps, Phantom); EIP-1193, SIWE (EIP-4361), EIP-712, ERC-20/721/1155/2771; Node.js (Express), Next.js, React.NET, PostgreSQL/SQLite/MS SQL, MongoDB (NoSQL), Docker; serverless, microservices, distributed systems (clustering), multithreading; CI/CD (GitHub Actions, Vercel). How I work: first-principles design → small PRs → strong tests → CI/CD → measured rollouts. I care about security, governance patterns, and reliability.
