I worked at Teleperformance as a Data Analyst, where I was responsible for managing, analyzing, and transforming large volumes of data into meaningful insights that supported business decision-making. My role required a strong understanding of data handling processes, attention to detail, and the ability to work efficiently under tight deadlines. Throughout my experience, I developed advanced skills in data entry, data cleaning, data reporting, and data analysis, ensuring accuracy, consistency, and reliability in every task I performed. One of my primary responsibilities was data entry, where I handled structured and unstructured datasets with high precision. I ensured that all information was accurately recorded, validated, and updated in the system. I worked with different types of data, including numerical, textual, and date-based information, maintaining a high level of accuracy while processing large datasets. My ability to work quickly without compromising quality helped improve overall operational efficiency. Data cleaning was another critical part of my role. I regularly identified and corrected errors, removed duplicates, handled missing values, and standardized data formats to maintain data integrity. Clean and well-structured data is essential for accurate analysis, and I took pride in ensuring that all datasets were reliable and ready for further processing. I used advanced Excel techniques to detect inconsistencies and applied logical methods to resolve data issues effectively. I also specialized in data reporting, where I created clear, insightful, and visually appealing reports for stakeholders. Using Microsoft Excel, I designed dashboards and reports that helped teams understand key performance indicators (KPIs) and business trends. My reports were structured in a way that made complex data easy to interpret, enabling better decision-making across different departments.
