Darko V.
Localization, Data Entry, and AI Info Quality Specialist
I’m a detail-oriented data specialist with 12+ years of experience in structured content QA, localization, and information integrity—with the past 3 years focused specifically on AI-generated content evaluation. Through long-term work with one of Upwork’s largest enterprise clients, I contributed to a large-scale knowledge base project that supports millions of users worldwide. My responsibilities have included: - Evaluating AI-generated content for accuracy, user intent alignment, policy compliance, and source grounding - Performing bilingual content localization (English ↔ Serbian) across a wide range of domains - Executing structured data curation, fact-checking, merging of duplicate topics, splitting of conflated topics, and QA tasks based on detailed internal guidelines I enjoy work that demands precision and consistency—especially when it supports real-world AI applications or improves the quality of public-facing data. I also hold a Bachelor’s degree in Pharmaceutical-Cosmetic Engineering, which developed my discipline for research, structured thinking, and quality control.
