What Will I Do as an Application Developer?

Application developers are in charge of creating software applications using the Python programming language. They are generally focused on the back end of websites or applications, i.e., the architecture, unlike front-end developers, who manage the visual aspects. 

An application developer’s role includes:

• Designing programs to function as clients need them to.
• Using critical thinking and creativity as they code.
• Identifying and implementing optimal tools for building or enhancing powerful, modular applications.
• Using tests to monitor applications and ensure the highest quality service.
• Providing technical and functional documentation of an application for clients and colleagues.
• Staying up-to-date with quickly evolving technologies - developers are lifelong learners!

What Will I Learn in This Training?

We will guide you at the beginning of your application development journey, helping you to set up a solid foundation for your training. You will discover software programming with one of the easiest languages to learn: Python.

Over the course of this training, we'll teach you a variety of skills, including how to:

• Develop a personalized learning plan and toolset.
• Use version control with Git and GitHub.
• Apply the fundamentals of programming in Python.
• Set up a Python environment.
• Manage data using ETL (extract, transform, load).
• Use object-oriented programming to develop a Python program.
• Structure the code of a Python program using a design pattern.
• Write robust Python code using PEP 8.

In addition to these technical skills, you will learn transversal or “soft” skills, which will help you grow as an application developer and allow you to progress in your career.

How Will I Learn at OpenClassrooms?

Our learning method is unique and revolves around two elements: professional projects and dedicated mentoring sessions.

Projects

At OpenClassrooms, learning is project-driven because that’s the fastest way to become proficient. Projects offer hands-on experience so you can hit the ground running when you start your new job.  

This path has three projects that you’ll need to complete, one at a time. You’ll receive a detailed brief with the context, customer requirements, and additional details. Then it’s up to you to go and make it real! To do this, you’ll have to be creative, coming up with innovative solutions to the questions at hand.

Mentorship

During your path, you will be assigned a mentor who will offer one-to-one support via weekly video conference sessions. This mentor will offer guidance on your projects, help define objectives, and coach you until you reach them. Our mentors are dedicated professionals who are experts in their field and have experience in sharing their know-how with our students.
