What I'm looking for

I am looking for a collaborative team environment that fosters growth and innovation.

I am a motivated and curious data science student with a solid understanding of Python, statistics, and data analysis. My journey in data science has been marked by hands-on experience in projects that involve data cleaning, visualization, and building machine learning models. I thrive on solving real-world problems through data, and I have developed a keen ability to find trends and insights from datasets.

In my recent role as an AI/ML Developer, I designed and trained a YOLOv8 model for vehicle detection, improving accuracy by 20%. I also built a real-time NLP system for sentiment analysis on Twitter data, showcasing my ability to apply machine learning techniques effectively. I am eager to join a team where I can apply my skills, gain practical experience, and continue to grow as a data scientist.
