I improve multilingual AI training data through precise transcription, annotation, translation, and quality assurance.
GermanyWhat I'm looking for
I transcribed, segmented, and validated multilingual audio and linguistic datasets as an AI Training Specialist, producing accurate DE/EN/RU/UA content for machine learning systems. I also improved grammar and text quality, translated between German and English, and recorded speech material for AI training.
Across Wisag, HFU International Center, Total Energy, and coffee sales and service roles, I've worked with structured data, documentation, international communication, customer support, and event coordination. I'm comfortable following complex guidelines, identifying inconsistencies, and maintaining accuracy in fast-paced, detail-critical work.
