#Software #Engineering - Lecture 9 : Software Evolution and Maintenance & Legacy System Management

#SoftwareEngineering #Course #HowToProgram #HowToCode #HowToBeEngineer Hello everyone. My name is Furkan Gözükara, and I am a Computer Engineer Ph.D. Assistant Professor at the Software Engineering department.

In this course, we will learn what is the true meaning of being a Software Engineer rather than being a web developer / freelancer developer / software developer / developer / coder / programmer, etc.
