Documentation Engineer · Technical Writer · Developer Education (DevRel) I turn complex developer and security topics into content people understand, use, and share. I ship documentation, maintain Git repositories, write technical content, educate developers, and build lightweight tools for crypto and blockchain projects. In this industry since 2020, from a journalism and editorial path (reporter to technical editor) to docs-as-code, engineering, and security self-learning. My comms background works well by delivering clear communication, research and fact-checking principles, and working with deadlines. Remote from Brazil, working worldwide. Independent contractor for single jobs or retainer work (15h/week per-project capacity).
