Freelancer Overview

As a freelance coding expert and senior data scientist, I bring a strong foundation in programming, data analysis, and AI training. At Outlier.ai, I contributed to large-scale model refinement by designing, correcting, and evaluating programming questions and AI-generated code in Python, JavaScript, C++, and Java. My critical thinking and programming accuracy were essential in ranking outputs, identifying edge cases, and fine-tuning model behavior. I combine my technical expertise with a solid background in finance and natural language processing (NLP). My work at RTE involved training and deploying NLP pipelines using Regular Expressions and Python to automate financial data analysis. I stand out through my attention to detail, multilingual capabilities (English, French, Arabic), and the ability to bridge technical and domain-specific challenges in diverse labeling environments.
