Development

Your limit is your imagination. There is no restriction on tech stack. You can do:

• Mobile App Development
• Website Development
• Desktop App Development
• AI/Machine Learning
• Blockchain
• IoT (Internet of Things)
• Cloud Computing
• Game Development (Unity)

and much much more...

1) Web Development

• FrontEnd
  1. To begin with frontend learn about HTML (HyperText Markup Language). HTML constitutes the basic structure and content of the website.

  Bonus : After learning about the basics of HTML , CSS , JavaScript, try exploring JS frameworks and libraries like Vue , React , Angular.
• BackEnd
  1. Install Xampp for running and testing the backend code (Only with PHP).

  2. Learn PHP to begin with backend programming.
  Link- https://www.w3schools.com/php/DEFAULT.asp
  Bonus : Explore other frameworks and libraries like
  • NodeJS ( https://www.w3schools.com/nodejs/) [Prerequisite - JavaScript]
  • Django ( (https://tutorial.djangogirls.org/en/) [Prerequisite - Python]
• Database
  1. Learn SQL (Structured Query Language) for setting up and manipulating MySQL DataBase.
  Link - https://www.w3schools.com/sql/
  
  2. Open the Xampp app and start the Apache server and MySQL database. Open a browser of your choice and head over to localhost/phpmyadmin. Try exploring the dashboard and its functionalities.
  Bonus : Try learning about NO-SQL databases (like mongodb , dynamodb , redis etc.) and the tradeoffs between SQL and NO-SQL.

2) Android Development (Native)

1. Books:
   • To learn Java: Head First Java/ Java- the Complete Reference (Herbert Schildt)

• Learn about databases (Refer to web slide for that purpose).
Bonus : Explore other JAVA frameworks like JAVAFX , Spring etc.

5) Machine Learning

• One stop resource to start with machine learning has to be the youtube playlist for machine learning by Andrew NG. (Link:Machine Learning — Andrew Ng, Stanford University [FULL COURSE])
• Learn a programming language like python to work with datasets.
Link: Python Tutorial by telusko (videos 1-70)
• After learning about the core concepts head over to Kaggle: Your Machine Learning and Data Science Community and explore the titanic dataset.
• After that explore other datasets like Housing Price Dataset and other beginner friendly datasets to get yourself started.
• You can also read the notebooks made by other Kagglers. If you ever get stuck they can throw some amazing insights into the dataset
