Course Description

Turn an idea into a working web application by learning the core tools and habits used in modern web development. This free online course guides you through the full stack: how pages are structured, styled, versioned, programmed, connected to a database, tested, and prepared for real-world deployment. Instead of treating web programming as isolated topics, you will see how each piece fits together to create dynamic, scalable applications.

You will start by strengthening fundamentals in HTML and CSS so you can build clean, accessible interfaces that look good across devices. From there, you will adopt Git as your daily safety net and collaboration tool, learning how to track changes confidently, experiment without fear, and keep a project organized as it grows. Next comes Python, where you will develop a solid understanding of how the language behaves and how to write clear, maintainable code.

With that base, you will move into server-side development with Django, a powerful framework for building data-driven web applications. You will learn to think in terms of reusable components, structured routing, and application architecture that makes sense for teams and long-term maintenance. You will also connect your application to a database using SQL and Django models, gaining practical insight into how data is stored, validated, and evolved over time through migrations.

On the front end, you will use JavaScript to add interactivity and improve user experience, including patterns that power smooth interfaces and single-page applications. Finally, you will explore professional practices that differentiate hobby projects from production software: testing strategies, continuous integration and delivery, and the essentials of scalability and security. By the end, you will be able to build, iterate, and ship web projects with a workflow that mirrors how modern developers work.
