Classification

Freelancer Overview

I have hands-on experience in data labeling and annotation at scale, having designed the labeling strategy and curated a dataset of 257,000 resume–job posting pairs for an NLP classification project. This included defining annotation criteria, ensuring data quality and consistency, and evaluating how labeling decisions impacted model performance (Sentence-BERT + LightGBM). I also work daily with AI output evaluation and prompt refinement as part of building a Conversational BI platform, giving me strong practical knowledge of RLHF-style feedback loops and AI training workflows.
