Freelancer Overview

I am a language professional specializing in translation, localization, and AI-assisted linguistic workflows, with several years of experience working across Greek, English, French, and Chinese. I hold a B.A. in French Language and Literature from the National and Kapodistrian University of Athens, a Diploma in Professional Translation, and specialized training in Machine Translation Post-Editing (MTPE). My background combines strong linguistic expertise with hands-on experience in evaluating, editing, and quality-checking machine- and AI-generated content within structured, process-driven environments. My professional experience includes multilingual translation and localization projects, linguistic QA, terminology management, and language-focused annotation tasks supporting NLP and AI training workflows. I have collaborated on projects related to major organizations and brands such as Johnson & Johnson, Metropolitan General Hospital, DEPA, GEK TERNA, Zagori, Emirates, and others. In parallel, I bring solid back-office and operations experience, including documentation handling, workflow-based task management, and structured written communication via email, ticketing systems, and digital platforms. I am detail-oriented, reliable, and comfortable working autonomously in fully remote, contract-based roles that require consistency, adherence to guidelines, and high-quality language output.
