Hi, I'm Marc-Aurele

Senior Web3 and AI engineer focused on smart contracts, developer tooling, agents and on-chain infrastructure. I build systems that make developers faster and products more reliable. My work spans Solidity, multi-chain infra, SDKs, payments, indexing and full-stack applications in TypeScript and Next.js.

Current focus areas: stablecoin payments, developer tooling, agents and AI assisted engineering workflows.

I care about developer experience and fast iteration. I prototype aggressively, ship often and explore new technical primitives around agents and applied AI for development.

Current Work

• PayXor: on-chain stablecoin payments with EIP-712 receipts, backend-authoritative pricing and multi-chain support
• VibeInProd: productionizing and hardening AI coded MVPs and agent generated software for founders

Selected Projects

• Fully on-chain NFTs with permanent metadata and content storage
• On-chain file uploads via chunked IPLD and Substrate based networks
• Self-hosted block explorer and indexing toolkit for custom chains
• Smart contracts and decentralized identity features for consumer apps
• SDK and CLI tools for smart contract development and refactoring
• LLM assisted development workflows and agent driven code loops

Technical Areas

• Smart contracts, protocol design and EVM internals (Solidity, Foundry, Hardhat, viem)
• Payments and stablecoins (EIP-712, signatures, backend pricing, multi-chain execution)
• Indexing and data access (SubGraph, SubQuery, SubSquid, Postgres, IPLD, custom indexers)
• Full-stack (Next.js, Node.js, TypeScript, React, Express, BullMQ)
• Developer tooling (SDKs, MCPs, CLIs, testing, CI)
• Agents and AI assisted engineering workflows
