What does a frontend developer do?

Frontend development is the discipline in charge of building the visible and functional part of a web or mobile application. That is, everything that the end user sees on the screen and can interact with. But not everything is as simple as we see, since a frontend developer has to combine visual design, programming logic, user experience (UX), performance and accessibility to create interfaces that are not only attractive, but also functional, efficient and universal.

Therefore, frontend development is a mix of:

• Visual design: The frontend developer converts a design (usually created by a graphic designer or UX/UI designer) into a functional and navigable page. This involves working with colors, fonts, spacing, sizes, icons, images and all the visual elements that make an interface look professional.
• Functionality and interactivity: Through JavaScript and modern frameworks such as React, Vue or Angular, the frontend allows users to interact with the application: display menus, submit forms, search in a list, change settings, etc. For example, when you type your name in a form field to register as a user and the site tells you that it is already in use, that is frontend.
• Responsive design: Nowadays, a website must look good and work correctly on any device: mobiles, tablets, laptops, big screens, etc. The frontend must adapt to all these situations, creating fluid and consistent experiences, regardless of the size or type of screen.
• Accessibility: A good frontend is not only for those who see and navigate without difficulties. It must also think of people with visual, cognitive or motor disabilities. That is why accessibility principles are applied, such as keyboard navigation, use of screen readers, adequate contrast, etc. This is an increasingly valued aspect (and legally required in some countries).
• Performance: Have you ever left a page because it took too long to load? Performance is also the responsibility of the frontend. Optimize images, reduce files, minimize the use of unnecessary JavaScript, load content progressively… All this influences the loading speed and user experience.

So… What is the day-to-day life of a frontend developer like?

• Translates designs into code: Takes design mockups (usually from Figma, Adobe XD or Sketch) and converts them into real web components using HTML, CSS and JavaScript.
• Creates interactive experiences: From sliders, forms, graphics and menus, to micro-interactions or subtle animations.
• Ensures the interface works on all devices: Applying responsive and mobile-first design techniques.
• Collaborates with designers, backend developers and product managers: This is a very collaborative role.
• Fixes visual and usability bugs: Polishing details is part of the constant work.
• Optimize web performance: Think about how to make everything load faster and more fluid.
• Implements accessibility and UX best practices: They make sure that anyone can use the app without barriers.

Profile of a frontend developer

The typical profile of a frontend developer combines creativity, attention to detail, and technical skills. This role usually suits someone who is comfortable working at the intersection of design and functionality, and who enjoys seeing immediate visual results from their work.

A good frontend developer has a keen eye for aesthetics and values clean, orderly, and visually appealing interfaces. There is a strong interest in user experience and a constant pursuit of clear, fluid, and intuitive interactions with the application. Detail orientation is key which means being able to notice when something is misaligned, when a color feels off, or when an animation doesn’t flow naturally.

Frontend developers also tend to have a creative approach, with a taste for experimenting with styles, transitions, and new ways of presenting content. At the same time, strong communication and teamwork skills are essential, as collaboration with designers, backend developers, and other professionals is a constant part of the job.

Finally, adaptability and a commitment to continuous learning are common traits, since the frontend ecosystem evolves rapidly and staying up to date with new tools, frameworks, and trends is essential.

And what does a backend developer do?

The backend is the invisible part of an application, but we could say that without it, nothing would work, since it is the engine, the brain, and many times, the part that stores sensitive information.

When you use an app or website, either to login, make a purchase or send a message, you are making the frontend communicate with the backend to process your request. This side that we don’t see is the one in charge of receiving the data, processing it, saving it, validating it and responding to the customer with the correct information. In other words: the backend is responsible for making things actually happen.

Therefore, backend development is a mix of:

• Data processing and business logic: The backend makes decisions. For example, if someone tries to book a flight, it is the backend that checks if there are seats available or the price to be charged. All this business logic, which varies from application to application, falls to the backend developer, who is responsible for defining and programming the rules.
• Connection with databases: One of the pillars of the backend is working with databases. Whether SQL (such as PostgreSQL or MySQL) or NoSQL (such as MongoDB), every modern application needs to store information about users, prices, products, posts, comments, etc. Therefore, the backend is the part that communicates with the database to read, write, update or delete that information as needed.
• Authentication and authorization: One of the most important roles of the backend is to manage security. Who can access what part of the app? How are credentials verified? What happens if someone tries to breach the system? Key functions such as registration and login, implementing authentication tokens (e.g. JWT), assigning roles and permissions, hashing passwords to protect them in case of leaks, and protecting against common attacks all come into play in this area.
• Creating APIs (Application Programming Interface): Today, many applications run through APIs: access points that allow the frontend, mobile apps or other services to communicate with the backend. A backend developer is responsible for designing, building and maintaining these APIs, making sure they are fast, secure, clear, well-documented and able to scale with the growth of the project.
• Integration with external services: Sometimes, an application needs to connect with other services such as payment gateways, mail sending, messaging systems, artificial intelligence, etc. The backend is responsible for integrating these external APIs and maintaining their correct operation.
• Performance, scalability and maintenance: A good backend must always have these fundamental aspects in mind. It is not just a matter of making the application work today, but also of thinking about the future: what will happen if tomorrow there are 100,000 users connected at the same time? Or if everyone connects at the same time? To avoid these problems, the backend must be designed to support high workloads, scale easily, avoid bottlenecks and have a clean, modular code architecture that facilitates its evolution.

What is the day-to-day life of a backend developer like?

A backend developer’s day typically starts by reviewing assigned tasks in project management tools like Jira or Trello, as well as checking in on the project’s status during team meetings (the well-known dailies). From there, the focus is mainly on writing and maintaining the code that handles the system’s logic, such as creating or updating APIs, designing databases, implementing business rules or integrating with external services.

Part of the day is also spent writing automated tests, reviewing teammates’ code (code reviews), and documenting features so that the team can understand and reuse what has been built. Backend developers also work closely with frontend developers to ensure APIs function properly, and with DevOps engineers or system administrators to deploy code to servers, configure environments, or monitor bugs.

In short, backend development is a role that blends logic, system design, security, efficiency, and teamwork, with a strong focus on application quality, scalability, and long-term maintainability.

Profile of a backend developer

The profile of a backend developer is often closely tied to logical, structured thinking and a strong orientation toward solving complex problems. These are individuals who enjoy understanding how things work behind the scenes and are drawn to building solid, efficient, and scalable systems. They tend to be interested in working with databases, data structures, business logic, security, and performance.

Those who choose this path usually have patience, attention to detail, and an analytical mindset. They find satisfaction in optimizing processes, seeing an API respond correctly, or watching a well-designed architecture handle a high volume of users without failing. They don’t need visual results to measure their progress: their motivation comes from the internal, stable functioning of the application.

They’re also typically interested in system security, resource efficiency, and writing clean, clear code. They enjoy planning, anticipating potential failures, and building solutions that can grow over time. In short, a backend developer enjoys working with logic, data, and complex structures, and feels comfortable being the “technical brain” that makes everything behind the interface work.

Conclusion: Frontend or Backend?

Choosing between frontend and backend is not simply about deciding between the visual and the logical, but about finding the path that best aligns with your interests and skills. If you are passionate about design, user experience and seeing immediate results on screen, frontend may be your thing. If you prefer to solve complex problems, work with data and build solid systems behind the scenes, the backend will be your natural space.

Both profiles require dedication, curiosity and constant learning, so the important thing is that you choose an area that motivates you to keep improving, that challenges you intellectually and that makes you want to create things that have a real impact.

And if you’re still not quite sure, that’s okay. You can always try both sides in small projects, experimenting, making mistakes and learning. Many developers start exploring both areas and then specialize or simply end up being full-stack.

Whichever path you choose, the essential thing is that you make that decision aligned with your interests, your way of thinking and the way you like to create. Because in development, as in any discipline, passion and perseverance make the difference.
