Freelancer Overview

I am an AI data annotation specialist with 1.5 years of hands-on experience supporting multimodal AI training project for Garmr, a U.S.-based startup, involving image and video data. I worked with proprietary annotation tools and MakeSense.ai to perform object detection, bounding box annotation, visual classification, and structured label assignment based on detailed annotation guidelines. My work also included dataset curation, quality-focused review, and handling ambiguous or edge cases to maintain annotation consistency and dataset reliability. In addition to visual annotation, I have experience contributing to multilingual AI training workflows through transcription, audio data collection, linguistic validation, proofreading, and structured data preparation in Belarusian, Russian, and English. My background also includes over 10 years of museum collection database management focused on archaeological artifacts, where I developed strong skills in systematic classification, precise visual analysis, and maintaining accuracy across large structured datasets.
