There, she learned how to use Python to analyze data from different companies and found the process very rewarding.

Prior to becoming a Data Analyst Consultant, Casiana worked at Microsoft, where she handled executive-level escalations and trained employees on best practices in data security. Her growing enthusiasm for data led her to The Information Lab, where she mastered data visualization tools such as Tableau, Alteryx and Power BI.

In her role as a Consulting Analyst, Casiana worked with a diverse range of clients, including charities, wealth management firms, hospitals, and universities. Notable clients include PWC, Buckinghamshire New University, Azets, and Reach Cambodia.

Outside of work, Casiana enjoys traveling, reading, writing, and spending quality time with her friends and family.
