What I'm looking for

I seek remote freelance or contract roles focused on proofreading, QA, and annotation for machine translation or narrative-quality projects, with clear guidelines and iterative feedback.

I am a native Brazilian Portuguese editor and QA specialist with hands-on experience in data annotation and quality review for LLM training platforms such as RemoteTasks and Appen. I provide line-level proofreading, structural feedback, and rewrites that preserve author voice while improving clarity and adherence to style guidelines.

I consistently deliver edits under tight deadlines, validate and normalize large volumes of user-generated text, and apply rigorous quality checks for relevance, intent, and policy alignment. I prefer freelance or independent-contractor roles (remote, Brazil) and bring strong attention to detail, remote-work discipline, and a passion for literature and narrative improvement.
