Bio

Welcome to My Profile!

I am Yosra Montasser, a native Arabic linguist with 15+ years of professional experience in English–Arabic translation, editing, proofreading, reviewing, and localization.

I hold a Bachelor’s degree in English Language and Translation from the Faculty of Al-Alsun (Faculty of Languages and Translation), Ain Shams University, and I am a ProZ.com Certified PRO (English > Arabic).

Throughout my career, I have worked across a wide range of fields, including UN and international development, hospitality, marketing, e-commerce, finance and economics, foreign exchange, technical content, IT and cybersecurity, healthcare, HR, education, and website localization.

In recent years, I have also expanded my linguistic work into AI language evaluation and quality review, contributing to projects involving AI-generated Arabic content, multilingual conversation evaluation, response assessment, RLHF/SFT workflows, audio annotation, and transcription review.

My work is built around three priorities: accuracy, natural Arabic, and attention to detail. Whether I am translating customer-facing content, reviewing a complex technical text, or evaluating AI-generated Arabic, I aim to produce language that is accurate, contextually appropriate, and natural to the target audience.

Professional Background

I began my career in 2010 at a publishing company, translating books and educational content. This experience gave me a strong foundation in accuracy, research, terminology, and attention to detail.

I later worked in the foreign exchange and financial news industry, translating time-sensitive English news into Arabic for FXStreet and MNI. The role required delivering accurate translations within extremely tight deadlines—often within 5–10 minutes—while maintaining linguistic quality and faithfully conveying complex financial information.

I then joined the translation department at Yellow Pages Egypt, where I worked extensively on company profiles, brochures, advertising campaigns, restaurant menus, hotel offers, and other marketing and business content in both English and Arabic.

Alongside my in-house experience, I have built an extensive freelance career working with international clients and language service providers on large-scale translation, localization, editing, and linguistic QA projects.

I have also completed several courses within the Translation Diploma program at the American University in Cairo (AUC), including Linguistics, Lexicography & Terminology, Arabic Grammar, Arabic Editing, Research Tools, Economic Translation, and Legal Translation.
