Becoming a programmer requires extensive practice, so it's important to engage in projects to compound your knowledge.

2. Get a degree

While it's usually optional to have a degree to become a computer programmer, having one can improve your chances of employment and career progression. You can pursue degrees in computer science, software engineering, mathematics, statistics and related disciplines. These courses can provide you with a better understanding of the underlying principles and concepts of computer programs. They also show you the relationship between the hardware and software, networks, operating systems, applications, automation and cybersecurity. You're also likely to learn about data privacy, information and technology regulations and the business side of the industry.

Besides university degrees, employers may also consider candidates who studied computer science or related courses in polytechnics. Another popular option for learning programming is a boot camp. Coding boot camps can be expensive or affordable, depending on the structure and intensity of the programme. These camps teach you to master programming in a specific language within a short period. The learning pace can be high, but they're an effective way to learn to program quickly.

3. Specialise

As a computer programmer, you can either specialise in operating systems or applications. Systems programmers build operating systems for computers, networks, servers, databases and cloud computing infrastructure. Working as a systems programmer requires proficiency in one or several operating systems.

Applications programmers create software for specific functions, and they can develop programs for mobile, desktop, games and the web. People who create mobile applications can create software and other products for mobile devices. Besides being a specialist, it's also important to be conversant with other programs, as clients and employers usually create products with cross-platform capabilities. That way, users can deploy a single software across different operating systems without issues.

4. Gain experience

Besides having traditional qualifications and completing online courses, employers want to see demonstrable coding experience before employing computer programmers. You can gain experience through internships, but these can be competitive. Internships provide the opportunity to work alongside experienced professionals who can provide mentorship and guidance. Another way to gain experience is through freelancing. You can join freelance websites and take entry-level coding work. As you gain experience and get better at marketing your skills, you can start applying for higher-level jobs that pay more.

Volunteering is another way to use your programming skills and gain valuable experience that can boost your CV.

Most programming projects take months from start to finish and often include several rounds of revisions, debugging and testing before delivery to the client or users. Many times, you may spend several days trying to find a bug in the source code that's affecting performance or security. Achieving these important tasks requires being patient.


Effective computer programmers are excellent communicators. The role typically involves working with a wide range of stakeholders, including software architects, project managers, quality assurance engineers, business managers, clients and other coders. Your work often requires writing, reading and discussing with other people on project requirements, task schedules, updates and a wide range of other issues.

Attention to detail

Computer programmers require a high level of attention to detail to produce clean, bug-free code. It's important to be detail-oriented when writing, editing and testing code, as even the smallest error can have serious implications for the performance and user experience of products. Being detail-oriented not only makes your work cleaner, but it can also reduce the workload of testers and quality assurance professionals and make people want to work with you.
