Marco contributed to the argotorg/sourcify repository by building and enhancing backend systems for smart contract verification and blockchain integration. He developed a contract data update and replacement toolkit with transactional safety, robust error handling, and API-driven batch processing. Marco improved the reliability and maintainability of verification workflows, refactored Etherscan integration, and expanded support for multi-version Vyper scenarios. He extended cross-chain verification capabilities, adding new networks and integrating RPC and API key management. Using TypeScript, Node.js, and Docker, Marco focused on scalable, maintainable solutions that improved data integrity, developer tooling, and network coverage, demonstrating depth in backend and DevOps engineering.

October 2025: Expanded cross-chain support for Sourcify with new networks and tests, implemented contract verification workflow across Etherscan, Blockscout, and Routescan, fixed data retrieval reliability, and enhanced DB/API key handling for cross-service verification. This work strengthens network coverage, data reliability, and developer tooling for faster verification and onboarding.
