What I'm looking for

I seek opportunities that foster innovation in AI and education, emphasizing collaboration and growth.

I am a versatile and results-driven data scientist with a strong academic background in Mathematics and Computer Science. My hands-on experience in AI training and large language model (LLM) development has equipped me with the skills to evaluate and enhance AI systems effectively. I am passionate about leveraging data and AI to drive innovation in education and intelligent systems.

Throughout my career, I have participated in various projects that involve evaluating AI-generated responses in mathematics and programming. My work has focused on ensuring accuracy, clarity, and logical coherence in model outputs. I have contributed to high-quality datasets and provided structured feedback to improve model performance, particularly in educational contexts.

As a freelance AI consultant and data scientist, I have worked on diverse projects involving data cleaning, feature engineering, and statistical modeling using Python and its various libraries. My goal is to continue pushing the boundaries of AI and data science to create impactful solutions that enhance learning and problem-solving capabilities.
