A day in the life

You arrive at 9am and join your team's daily standup—a 15-minute catch-up on what everyone's working on. By 9:30 you're deep in your code editor, building a new feature for a mobile app. Mid-morning you pair with a colleague to debug a tricky issue, bouncing ideas back and forth until it clicks. After lunch you review a teammate's code and leave some helpful comments, then spend the afternoon writing tests to make sure your new feature works correctly. At 5pm you push your code, and somewhere a real user will benefit from what you built today.
