a day in my life
As a Data Engineer
I build systems that collect, manage, and convert raw data into usable information for data scientists and business analysts to interpret. My ultimate goal is to make data accessible so that organizations can use it to evaluate and optimize their performance.
As a Data Analyst
I bring together theory and practice to identify and communicate data-driven insights that allow managers, stakeholders, and other executives in an organization to make more informed decisions.
As a Data Scientist
I work closely with business stakeholders to understand their goals and determine how data can be used to achieve those goals. Then design data modelling processes, create algorithms and predictive models to extract the data the business needs and help analyze the data and share insights with peers
