Download Resume Recent ProjectsThrough my work with multiple clients, I realized the importance of precision in data processing and predictive analytics when it comes to profitable decision-making. Therefore I have been mastering the art of data through mainly Python, SQL, PySpark, and many different packages to cut the noise in data sets, detect anomalies, and create models that answer the business challenges at hand. During my free time, I find joy in design, fashion, and data visualization. Paired with a unique blend of technology and business background, I am adaptable when choosing data tools and effective when communicating with both engineers and business stakeholders.
