About the website

 

A while back, I completed an intensive programming course called - 100 Days of Code: The Complete Python Pro Bootcamp on Udemy.

It enabled me to master the Python programming language by working on many uniqe projects over 100 days.
Through this course, I acquired comprehensive skills in:

  • Automation: Mastered tools like Selenium and Beautiful Soup to automate tasks in Python.

  • Web Development: Learned to create fully functional websites and web applications using Flask.

  • Data Analysis and Machine Learning: Gained proficiency in working with libraries such as Pandas, NumPy, Scikit Learn, Plotly, and Matplotlib, 
    essential for data analysis and building machine learning models.

  • Game Development: Developed games like Space Invader, Pong, and Snake, which helped me understand advanced programming concepts.

  • Desktop Application Development: Built graphical user interfaces and desktop applications using Tkinter.

  • API Development: Created and integrated APIs, enhancing the functionality of my applications.
     

Each project in this course was an opportunity to apply newly acquired knowledge and hone my programming skills. Completing this course has provided me with a solid foundation and the confidence to effectively program in Python at a professional level.

Inspired by what I learned, I decided to build my portfolio website. Here it is... 😁

The website is designed like a blog, enabling the addition, editing, and deletion of posts (restricted to admin user). Each post is crafted using the CKEDITOR 5 web editor and stored in a PostgreSQL database.
