Freelancer Overview

Native Hebrew speaker with fluent English and over a year of experience in content moderation, quality control, and AI assessment at Tech Mahindra, where I evaluated written content for grammar, accuracy, structure, and safety across digital platforms. My background includes rigorous fact-checking, editing, and working with spreadsheets and data management tools, skills that are strengthened by my Level 4 Certificate for Accounting Technicians and IBM Data Analytics Essentials certification. This combination of linguistic precision, analytical thinking, and attention to detail allows me to handle translation, proofreading, and content work with both accuracy and efficiency. I'm proactive, deadline-driven, and comfortable adapting to different project requirements while maintaining high standards throughout.
