    Hi! My name is Alice Zhang, and I am a recent data science graduate from UC Santa Barbara with a strong background in data analytics, statistics, and programming. I was born and raised in the Bay Area, and recently returned back here after graduating. I'm currently seeking opportunities to grow my skills and contribute meaningfully in a professional setting. Throughout my academic and professional journey, I've gained hands-on experience in data cleaning, visualization, analysis, and modeling, such as: * Building machine learning projects in R and Python, where I traversed the data cycle life cycle to analyze fertility rates and predict loan eligibility, OR * My internship at Diversified, where I mined large-scale project dashboards for actionable insights to support strategic decision making. Additionally, my role as a Peer Advisor honed my teamwork and leadership skills, while being a staff writer for The Daily Nexus strengthened my ability to synthesize complex ideas clearly and effectively. I thrive at the intersection of analytics and storytelling, and I'm eager to bring my skills to Upwork. Please feel free to contact me at alicegrcez@gmail.commor 4089338665!
