Multilingual QA Specialist | Evaluating AI & human responses for accuracy, safety and policy alignment.
UkraineWhat I'm looking for
I’m an analytical, multilingual operations and quality professional with a philological background, and I specialize in high-stakes compliance and team coordination. In my current Support Shift Leader role, I manage complex ticket escalations and perform high-level reviews of AI responses to ensure they address user concerns while aligning with internal safety guidelines.
I translate QA insights into coaching frameworks that measurably improve performance, including driving a 20% increase in team-wide efficiency. I also bridge cross-functional needs—partnering with technical, legal, and marketing teams—to resolve incidents and refine workflows, while applying strict rubric-based assessment to multilingual nuance. I’m now seeking to leverage this linguistic judgment in a dedicated AI Evaluator role.
