What I'm looking for

My professional interests center on multilingual LLMs, human evaluation, terminology, language technology, and data-driven evaluation. I’m building my computational skills to support multilingual NLP and LLM evaluation workflows.

At Yandex, I lead and support a Turkish-language AI evaluation team, reviewing AI-generated content and evaluation decisions against detailed rubrics for accuracy, relevance, instruction following, and linguistic quality. I resolve ambiguous cases and help calibrate reviewers so judgments are consistent.

As a freelance translator and reviser, I work between English and Turkish on localization, translation, and linguistic QA. I’m also developing my computational skills through Miuul’s Data Scientist Bootcamp, with a focus on Python, data analysis, statistics, and machine learning.
