Massimiliano Pippi
Italy
Summary
🤩
RockstarMassimiliano Pippi is a seasoned backend and DevOps engineer based in Italy with 15 years of experience building reliable, production-grade systems. He has contributed to and shipped features for prominent open-source projects and companies including Datadog, Elastic, Arduino and community tooling like Django OAuth Toolkit and GNS3. His work spans low-level integrations (C APIs to expose Datadog aggregators to Python), Terraform provider improvements, CI/CD and observability, and practical refactors that simplify build and deployment flows. He’s comfortable across stacks—from Go and C integrations to Python backend and CLI tooling—and has improved test coverage and logging in complex systems such as Haystack’s Weaviate integration. Notably, he combines hands-on implementation with technical writing and CI automation, often tackling the subtle edge cases (e.g., Windows time precision, Zookeeper version parsing) that make systems robust. For direct contact he points visitors to dev.pippi.im rather than LinkedIn.
