A Day in the Life
A typical day involves morning standup, then diving into feature work or bug fixes. You might spend the morning writing an API endpoint and its tests, have a design review over lunch, then spend the afternoon optimizing a slow database query. Code reviews, oncall rotations, and cross-team syncs round out the week.
