Freelancer Overview

I am a Software Engineering student at the University of New Brunswick with experience in AI evaluation, data annotation, machine learning, and software development. I have worked as an AI Data Annotator with Outlier AI for over a year, contributing to AI training and evaluation workflows involving text analysis, response rating, reasoning evaluation, and quality assurance tasks. I also worked as an AI Chatbot Tester at Testlio, where I evaluated conversational AI systems for accuracy, consistency, usability, and hallucination detection. My background includes designing structured evaluation workflows, identifying edge cases and reasoning issues, and providing detailed feedback to improve AI model performance. In addition to AI-focused work, I have built machine learning and data engineering projects involving ETL pipelines, predictive modeling, and real-time data visualization using Python, scikit-learn, React, Django, and pandas. I am particularly strong in analytical reasoning, technical problem-solving, quality assurance, and written communication.

TextEvaluation/Rating

As an AI Data Annotator at Outlier AI , I worked on AI training and evaluation tasks involving text annotation, response ranking, reasoning analysis, and quality assessment for large language models. I evaluated AI-generated responses for factual accuracy, clarity, consistency, instruction-following, and logical reasoning across a variety of prompts and workflows. I provided structured feedback to improve model performance, identified hallucinations and response issues, and followed detailed annotation guidelines to maintain high-quality evaluation standards. The role required strong analytical thinking, attention to detail, written communication, and the ability to assess nuanced AI behavior across different scenarios.
