Brazilian Physician | Medical Translator | AI Medical Review

I bring physician-level medical expertise to translation, content review, and AI-generated medical content. I’m a Brazilian physician trained in Internal Medicine with extensive clinical experience and more than a decade working with complex medical documentation in English and Portuguese. My work sits at the intersection of medicine, language, and technology. I help organizations translate, review, and validate medical content, ensuring that the reasoning, terminology, and clinical meaning remain accurate. I have collaborated with healthcare institutions and medical organizations, including Stanford Medicine Children’s Health, as well as pharmaceutical translation projects for AstraZeneca. Because of my medical background, clients often bring me in when precision truly matters — clinical documentation, medico-legal material, and health-related reports where nuance and technical correctness are essential. I frequently work with: • Clinical reports, discharge summaries, and hospital documentation • Medical records and physician documentation • Psychological and psychoeducational evaluations • Special education documentation and IEPs • Patient education and healthcare materials Beyond translation, I also assist with: • Medical translation review and proofreading • Terminology consistency across complex documents • Validation and correction of AI-generated medical content • Adaptation of healthcare materials for Brazilian Portuguese I’m particularly interested in projects involving medical AI evaluation, clinical reasoning validation, and the review of AI-generated medical content. As a practicing physician, I focus not only on whether an answer is correct, but on whether the underlying pathophysiology and clinical logic actually make sense. Work with me when you need physician-level medical expertise behind your translation or content review.
