To me, as I advanced in programming, I came to realize the true difference between programming and software engineering. Software engineering is applying engineering principles to build software web applications, desktop applications, mobile apps, or services. But as you progress, you see it's much more about collaboration. Working with other engineers to architect, design, build, test, implement, and deploy robust, high-performance, predictable systems that can evolve over time. Programming is writing code to solve a specific problem. And that's part of it. But software engineering is the broader discipline. Collaboration and process that make those solutions durable and scalable. The gist is, programming focuses on writing code to solve a problem. Software engineering includes that, and adds design, architecture, testing, deployment, and teamwork to build systems that last.
