Hire the Best Academic Writing Specialists
in Portugal

I specialize in language, communication, and AI-related content, combining my background in linguistics, teaching, and real-world customer interaction. With a degree in Portuguese and English Studies and a CELTA certification from Cambridge, I have developed strong skills in linguistic analysis, cross-cultural communication, and content evaluation. My work focuses on how meaning, tone, and nuance are constructed — especially in contexts involving interaction between humans and language models. I have experience in teaching and customer-facing roles, which allows me to understand language not only from a theoretical perspective but also in real-world communication. This helps me evaluate clarity, intent, and naturalness in written content. I am particularly interested in: - Language model training and evaluation - Content annotation and refinement - Translation (English ↔ Portuguese) - Proofreading and linguistic review I bring attention to detail, cultural sensitivity, and a critical approach to language. If you're looking for someone who understands both the structure and the subtlety of communication, I’d be glad to contribute to your project.
