Creating predictive models using machine learning
-
Building dashboards and visualizations
-
Helping businesses make data-driven decisions
Data Scientists work heavily with Python, R, SQL, Tableau, TensorFlow, Pandas, and machine learning algorithms.
What Does a Full Stack Developer Do?
A Full Stack Developer builds complete web applications — both the front-end (user interface) and back-end (server-side logic).
Their responsibilities include:
-
Designing user interfaces
-
Creating APIs
-
Managing databases
-
Handling server operations
-
Deploying applications
-
Ensuring website responsiveness and performance
