  As a skilled Data Scientist and Power BI Developer, I have worked as a freelancer on Upwork for over two years, delivering high-quality data-driven insights and visualizations to clients across various industries. Using my strong analytical skills and expertise in programming languages like Python and R, I have developed custom solutions for data collection, cleaning, analysis, and modeling. I am also proficient in SQL and have experience working with various databases. Additionally, I have extensive experience creating interactive dashboards and reports using Power BI, enabling clients to make data-driven decisions in real-time. As a result of my strong work ethic and ability to communicate effectively, I have received excellent feedback and repeat business from clients.As a Data Scientist and Power BI Developer, I worked on a project for a university canteen to develop a solution that would help them manage their inventory and reduce food waste. I conducted a time series analysis on historical sales data to forecast future food demand and created a Power BI report that visualized daily sales, customer demographics, demand forecasts, and food wastage. The report allowed the canteen staff to easily track and analyze their daily operations, identify areas of improvement, and make data-driven decisions to optimize inventory management and reduce waste. As a result of this project, the university canteen was able to reduce food waste and optimize their inventory management, leading to significant cost savings.During my time at Vida Select, an online dating platform, I developed a machine learning model using k-means clustering to segment users and improve the match-making process. The model helped users find their perfect match, resulting in a high success rate of marriages among users. This improvement to the platform led to a significant increase in sales and user engagement Show less
