Projects

ATP Sports Betting - Machine Learning Project - Python

The goal of this project is to develop a machine learning model that can predict the outcome of a tennis match based on the names of the two players and some other features. The project uses ATP data from 2018, which contains information about the matches played in that year.

Data Analysis & Web Scraping - Python & Power BI

In this project, I scraped data from an online furniture store, focusing on DOOS Design’s products and prices compared to competitors. Visualizations were created to enhance DOOS Design’s market position and sales.

Data cleaning and transformation - Excel

This project demonstrates how to use Excel to perform data analysis on a bike sales company. The goal is to understand the characteristics and preferences of the customers, such as their age, gender, and location.

Advanced Dashboard Creation - Excel

In this Excel project, I created an interactive dashboard with a timeline and slicers to compare coffee sales across different types. This advanced Excel tool now serves as a powerful resource for data analysis and visualization.

Interactive Dashboard for British Airways Reviews - Tableau

In this interactive Dashboard for British Airways Reviews, I developed a comprehensive dashboard that allows end-users to filter and analyze customer feedback data effectively.

Experience

Jr. Data Analyst at Doos Design

In my role, I focused on Sales Opportunity Identification and Discovery. Through tireless effort, I uncovered data-driven opportunities that exceeded industry standards. By strategically analyzing competitors and utilizing web scraping, I revealed valuable insights that positioned us advantageously in the market. I also led the Competitor Analysis process, employing a meticulous approach to uncover hidden gems. Notably, our rivals priced their comparable products 13-30% higher, giving us a competitive edge. Furthermore, I collaborated closely with sales agents in Data-Driven Sales Planning and Dashboard Creation. Together, we devised sales strategies fueled by data, resulting in real-time updates and a quantifiable boost in collaboration and sales efficiency.
