Software development is at the heart of the digital transformation we are experiencing. From the mobile apps we use every day to the systems that control infrastructures, vehicles, companies or artificial intelligence, everything works thanks to professionals who know how to write, maintain and optimise code.

If you are thinking about working in this sector, it is normal that you have doubts: What do I have to learn? What languages do I need to master? How do I start? Do I need a university degree? Don't worry. In this article we give you a clear and realistic guide on what you need to know to start your way in the world of software development.

7 things you need to know to become a software programmer and developer

1. Have a problem-solving mentality

Before even talking about languages or frameworks, there is one skill that defines any good developer: the ability to solve problems. Programming is essentially about finding efficient solutions to concrete challenges, from how to store data to how to make an app fast and secure.

So if you enjoy breaking down complex problems into simpler steps, experimenting, learning from your mistakes and constantly looking for the best solution, the Full Stack Development degree may be what you're looking for.

2. Learn how to really program

This may seem obvious, but there is a big difference between knowing how to copy code from the internet and really understanding how a programming language works. If you want to work as a software developer, you will need to master at least one or two languages in depth.

Some of the languages you will need to master to make your profile attractive are:

JavaScript / TypeScript - a must for web development.
Python - ideal for automation, data science, AI or backend.
Java / C# - widely used in enterprise applications.
C / C++ - if you are interested in systems development or video games.
Swift / Kotlin - if you're interested in mobile apps.

Beyond that, you will need to understand data structures, algorithms, programming logic and concepts such as asynchrony, object-oriented programming or version control (Git).

In UDIT's Bachelor's Degree in Full-Stack Development you will learn from the first year to work with these programming languages and development environments through real projects and teamwork.

3. Mastering web development (frontend and backend)

Nowadays, a very important part of the software that is developed is designed for the web. Therefore, knowing the technologies that shape the internet is key for almost any technical profile: on the one hand, the frontend (what the user sees): HTML, CSS, JavaScript, React, Vue or Angular and, on the other hand, the backend (server logic): Node.js, Python (Django/Flask), Java (Spring), databases such as MongoDB or PostgreSQL, REST APIs and GraphQL.

With the Degree in Full Stack Development you will get the most complete programmer profile by combining knowledge of the server side (Back-End) and the client side (Front-End), a versatility highly valued by companies.

4. Understand how the software we use every day works.

Writing code is not enough. To be a good software developer, you also need to understand how the systems your code runs on work: browsers, servers, networks, web architectures, protocols such as HTTP, etc.

You should also learn about databases (relational and non-relational), good security practices, scalability and optimisation. The more you know about the "ecosystem" where your code lives, the more effective you will be as a professional.

5. Work in a team and communicate well

Although the image of the solitary developer programming in his room still exists in the collective imagination, the reality is that software development is a team effort.

You will need to communicate with other programmers, designers, product managers and end users. Learning to collaborate, documenting your work, doing code reviews and contributing in meetings will be part of your day-to-day life.

That's why at UDIT we give so much importance to soft skills: we don't just train programmers, but also people prepared to lead projects and contribute real value to any company or product.

6. Create a portfolio of real projects

One of the keys to getting your first job as a developer is to be able to demonstrate what you know how to do. Companies greatly appreciate it if you have a portfolio of personal or academic projects where they can see your code, how you structure an app, how you work in a team or how you solve technical problems.

So, if you are just starting out, focus on creating things like a personal website with your CV, a blog made from scratch, an API to manage users or products or an app with a database and authentication.

In UDIT's Full-Stack Development Degree, all our students work from the first year on real projects, and end up with a solid portfolio that differentiates them in the job market.

7. Keep up to date and never stop learning

Technology is constantly changing. What is trendy today may be obsolete tomorrow. That's why, if you want to work in software development, you must have a continuous learning mentality.

Reading documentation, taking online courses, following industry leaders, collaborating in open-source projects or participating in hackathons are great ways to keep up to date.

And if you choose an education like UDIT's, you will always be in touch with the latest technologies, tools and methodologies used in the real industry.

How do I start training as a full stack software developer?
