Freelancer Overview

Worked with Data Annotation on mainly Russian Language projects involving prompting till failure, fact checking and other quality assurance projects. In my private life I've finetuned models and created RL pipelines from scratch which involved creating algorithms to filter data which was later fed into an AI model via QLora.
