1. Responsive Web Design

You’ll master the languages that developers use to create webpages in this Responsive Web Design Certification: HTML (Hypertext Markup Language) for content and CSS (Cascading Style Sheets) for design.

To understand the fundamentals of HTML and CSS, you’ll first create a cat photo app. Later, you’ll design a penguin to master modern techniques like CSS variables and a web form to learn best practises for accessibility.

Finally, by creating a Twitter card with Flexbox and a complicated blog layout with CSS Grid, you’ll learn how to create webpages that respond to varied screen sizes.

2. JavaScript Algorithms and Data Structures

JavaScript is used to make a page interactive, whereas HTML and CSS manage the content and appearance. You’ll master the essentials of JavaScript, including variables, arrays, objects, loops, and functions, in the JavaScript Algorithm and Data Structures Certification.

You’ll use your newfound knowledge to create algorithms that manipulate strings, factorialize numbers, and even compute the orbit of the International Space Station once you’ve mastered the foundations.

You’ll study two fundamental programming paradigms along the way: Object Oriented Programming (OOP) and Functional Programming (FP) (FP).

3. Front End Development Libraries

You’ll learn how to style your site rapidly with Bootstrap in the Front End Development Libraries Certification. You’ll also learn how to use Sass to expand and add logic to your CSS styles.

Later, you’ll design a shopping cart and other applications to learn how to use React and Redux to create powerful Single Page Applications (SPAs).

4. Data Visualization

Data is all around us, yet it’s meaningless without context or shape.

With the D3.js package, you’ll create charts, graphs, and maps to present various sorts of data in the Data Visualization Certification.

You’ll also learn JSON (JavaScript Object Notation) and how to use an API to work with data online (Application Programming Interface).

5. Back End Development and APIs

Microservices, which are small, modular programmes that work together to form a larger whole, are one of the most common ways to build apps today.

You’ll learn how to develop back end apps using Node.js and npm in the Back End Development and APIs Certification (Node Package Manager). You’ll also use the Express framework to create web applications, as well as MongoDB and the Mongoose library to create a People Finder microservice.

6. Quality Assurance

You’ll want to test your programmes or web applications as they become more complicated to ensure that new changes don’t break their initial functionality.

You’ll learn how to build tests with Chai to guarantee your apps work as expected in the Quality Assurance Certification.

Then, to learn advanced Node and Express principles, you’ll develop a chat application. Pug will be used as a template engine, Passport will be used for authentication, and Socket.io will be used for real-time communication between the server and connected clients.

7. Scientific Computing with Python

Python is one of today’s most popular and versatile programming languages. Everything from simple scripting to machine learning can be done with it.

You’ll master Python foundations including variables, loops, conditionals, and functions in the Scientific Computing with Python Certification. Then you’ll move on to more advanced topics like sophisticated data structures, networking, relational databases, and data visualisation.

8. Data Analysis with Python

Data analysis has been practised for many years. Developers used pricey, closed-source tools like Tableau to do it until a few years ago. However, Python, SQL, and other open libraries have recently revolutionised Data Analysis.

You’ll master the principles of data analysis with Python in the Data Analysis with Python Certification. By the completion of this certification, you’ll know how to read data from CSVs and SQL files, as well as how to process and visualise data using libraries like Numpy, Pandas, Matplotlib, and Seaborn.

9. Information Security

With everything we do online, we put a lot of personal data at risk: email addresses, passwords, phone numbers, and so on.

With the Information Security Certification, you’ll learn the fundamentals of protecting people’s information online by building a secure web app with HelmetJS.

In Python, you’ll also create a TCP client, as well as a Nmap and port scanner. This will assist you in learning the fundamentals of penetration testing, which is a vital aspect of information security.

10. Machine Learning with Python

You’ll utilise the TensorFlow framework to build many neural networks and study more advanced techniques like natural language processing and reinforcement learning in the Machine Learning with Python Certification.

You’ll also study the fundamentals of neural networks, including how deep, recurrent, and convolutional neural networks work.

11. Coding Interview Prep

We’ve got you covered if you’re seeking for free coding activities to help you prepare for your next job interview.

Hundreds of code challenges are available in this section, which will put your knowledge of algorithms, data structures, and mathematics to the test. It also includes several take-home projects that you can utilise to hone your abilities or expand your portfolio.
