I am a highly motivated professional with a strong foundation in theoretical mathematics and a proven track record in AI training, machine learning model development, and data annotation. I combine rigorous mathematical reasoning with practical ML implementation to improve model correctness and performance.

In freelance and project work I have developed and optimized models using Python, TensorFlow, and PyTorch, and delivered measurable results such as a 20% improvement in retention strategies through a customer churn prediction model. I have also implemented NLP solutions for sentiment analysis to improve product feedback loops.

I bring extensive hands-on annotation and QA experience — annotating hundreds of audio datasets, recording and validating 200+ audio sets, and performing audio quality assurance and software bug hunting. I have provided virtual assistance, localization, translation, and transcription support while collaborating across Data Science and Engineering teams to meet project goals.

I hold a bachelor's degree in Computer Science and relevant certifications in AI and TensorFlow. I am committed to continuous learning, high attention to detail, and contributing to teams that value rigorous model evaluation, robust data pipelines, and measurable impact on AI product quality.
