Software Engineering

Software EngineerBackend DeveloperFull-Stack EngineerTech Lead

Programming is making a computer do something. Software engineering is doing it in a team, on a codebase that outlives you, without breaking production. This path covers readable code, testing, design, APIs, security and the judgement that separates a developer who ships features from one who is trusted with a system.
