Your Users Experience Your Backend Too.
For a long time, whenever we hear 'User Experience', we instinctively think of UI/UX designers, product designers, or maybe frontend engineers. Why? Because we tend to think users interact first with a graphical or command-line interface, while the backend engine plays little to no role in how they experience the product. The first half is correct. The second half, incorrect. A user doesn't…
User experience extends far beyond the user interface. While most focus on UI/UX designers and frontend engineers, the backend plays a crucial role in shaping the user's overall experience. The backend is not just about the functionality of endpoints or the technical soundness of architecture; it's about how these technical decisions impact what the user feels and sees.
API response times directly affect user experience. Users are concerned with the immediacy of their interactions, not the number of database queries or the service's cold starts. A three-second delay in a "Pay" button press can lead to abandonment if not addressed. Similarly, error messages are a direct reflection of UX. A generic "400 Bad Request" doesn't help the user. Instead, a specific message like "Your payment could not be completed because your card was declined" provides clarity and direction.
API design, though abstracted from the user, heavily influences UX. The frontend builds products using these responses. Overly complex APIs requiring multiple requests to perform a single task can lead to excessive loading states and complicated frontend logic, all of which degrade the user experience.
System architecture choices, particularly in asynchronous processing, can make or break the user experience. For instance, processing a large file should not require users to stare at a loading screen until the end. Instead, acknowledging the request, processing it in the background, and notifying the user upon completion creates a smoother experience.
Lastly, scaling architecture choices directly impact user experience. While a system may function well with a small user base, it can become frustrating with a larger one. If an application slows down during peak usage, users perceive it as a problem with the application itself, not the infrastructure, leading to frustration. As software becomes easier to create, the focus should shift to making good technical decisions to enhance the user experience.
