Marco contributed to the libp2p/test-plans repository by building and enhancing interoperability testing frameworks and CI/CD infrastructure, focusing on distributed systems and protocol validation. He upgraded Go version locks and Makefiles, introduced checksum verification, and expanded test matrices to cover multiple go-libp2p releases, ensuring reliable and reproducible test environments. Using Go, Rust, and Python, Marco developed a GossipSub interoperability testing framework with Shadow-based simulation, enabling cross-language validation under varied network conditions. Additionally, he improved artifact handling in GitHub Actions workflows and delivered editor enhancements for zed-industries/zed, implementing symbol highlight navigation in Rust to streamline code comprehension and debugging.
In September 2025, delivered a focused editor enhancement for the zed project to improve navigation of symbol highlights. The Document Highlight Navigation feature adds go-to-next/go-to-previous highlight capabilities, enabling developers to quickly traverse occurrences of a symbol and follow data flow, which accelerates debugging and code comprehension. This work aligns with issue #35994 and is backed by commit 14ffd7b53fb69cbee6e979efe5fc0ea5ece101f7. Business value: faster symbol tracing, reduced context-switching, and higher developer productivity across the codebase.

June 2025: Go Version Lock Management and Checksum Verification for Transport Interop Tests in libp2p/test-plans. Updated Go version locks and Makefiles to support Go 0.41, removed outdated locks for 0.36, 0.37, and 0.39, and added checksum verification for Go 0.41 while ensuring verification is invoked for Go 0.40. This work stabilizes interop test matrices, reduces drift, and strengthens CI reliability across Go toolchains.
