I specialize in language processing tasks like named entity recognition, text classification, and sentiment analysis, and I maintain strict quality control to ensure consistency across large datasets.
I’ve collaborated with teams at Banque Internationale à Luxembourg (BIL) and Nebius Group, developing annotation guidelines, tools, and QA processes. I enjoy turning complex data into reliable, well-labeled resources that help AI models perform better in real-world scenarios.
