Which Career to Choose: Programmer Vs System Administrator

Careers in the technology space and broad and diverse and require different sets of skills. Programming and Systems Administration are two occupations that stand out and you are likely to find professionals in these fields in almost every company.

The rising demand for programming and administration skills has opened doors to freelancers who bridge the gap and work for companies seeking experts in the same field.

In this tutorial, we explore differences between Programmers and System administrators, more specifically in terms of the skillsets.

Who is a Programmer?

Programming is the process of writing code to create an application or program that carries out specific tasks.

A programmer is an IT professional who writes code, which constitutes a software application or program. A typical application or program can have hundreds or even thousands of lines of code depending on its complexity.

A computer programmer is sometimes referred to as a software developer and the two can be used interchangeably to refer to the same thing. However, there’s a perpetual debate as to the differences between the two professionals and the scope of responsibilities that programmers and developers can undertake.

There is a bucketful of programming languages in use today. Popular examples include Java, Python, Go, RUST, C, C++, C#, Javascript, and PHP. Although not categorized as programming languages, HTML and CSS are the backbone languages for front-end web development.

The proliferation of programming languages has led to the emergence of various programming niches in the tech industry. Programming has grown in leaps and bounds and rapid growth in the tech industry has led to the emergence of various programming niches.

Let’s explore some of these categories of programmers.

Frontend Developers

Front-End developers are professionals who specialize in designing the visual components of a website or web application. They are tasked with creating the UI (User Interface) of websites and ensuring smooth and immersive UX (User Experience).

As the name suggests, Front-End developers design the look and feel of the websites and ensure all the elements are aesthetically appealing and responsive to user interaction and input. As a Front-End developer, you need to be creative enough in order to visualize how websites will appear to visitors and potential clients.

Must-have skills for front-end developers include:

HTML & CSS
Javascript, TypeScript
Frameworks such as Bootstrap, React, Angular and Vue.JS
Cross-browser compatibility
Responsive Design
Version Control such as Git.

Backend Developers

Backend refers to everything that happens behind the visual aspects of a website or application. A good example is when you click a button that performs a certain task.

For example, when you click the ‘Sign Up’ or ‘Send Up’ button, although it’s part of the visual aspect of the website, what it actually accomplishes is what is referred to as the backend.

The backend mostly entails server processes, APIs, and interactions with complex and large-scale databases.

Ideally, backend developers should have a firm grasp of front-end languages such as HTML, CSS, and Javascript to be able to work efficiently. However, more importantly, they need a solid foundation in backend technologies such as:

Java
Python
Perl
.NET
Ruby on Rails
Node.JS
C
Database technologies such as SQL, PostgreSQL, and NoSQL databases such as MongoDB and Redis.
API development
Testing and Debugging Tools
Git Version Control

Fullstack Developers

If you combine the skills of a front-end and back-end developer, you end up with a full-stack developer. A full-stack web developer is tasked with developing websites from the ground up: from the visual elements such as the website layout, typography, and responsiveness, to the backend architecture.

As a result, a full-stack developer is one of the most valuable and sort after developers and commands an attractive pay package. Expectedly, a full-stack developer will have a combination of skills drawn from a front-end and back-end developer.

Mobile Developers

Mobile applications – both Android and iOS – are a critical part of our everyday life. You use them every day, whether you are on social media, ordering lunch or dinner, checking out the news or weather, or simply playing a game on your phone.

Mobile developers are professionals who develop and test mobile applications, which requires a skill set in the following languages:

Java
Kotlin
Swift – For iOS apps
Objective C
React Native
React.JS

Database Developers

Databases are ubiquitous and any tech stack, cloud application, or centralized enterprise application relies on one or more databases to store and replicate data. The more intricate an application is, the more the need for stable and robust database management systems.

A database developer is a professional with mastery of how databases work. Database developers create and maintain databases and ensure efficient storage of data. In addition, they are responsible for designing and implementing new databases and ensuring existing ones are well-updated and tweaked to accommodate changing requirements of the application.

A database developer needs to have the following set of database skills:

SQL relational databases such as MySQL, PostgreSQL, Microsoft SQL server, etc.
NoSQL databases including MongoDB, Redis, Apache Cassandra, CouchDB, etc.
Oracle
IMB DB2
Data Analysis
Linux / UNIX operating systems.

Game Developers

The global video game industry is an enormous industry that has taken the world by storm for a while now. Revenue from the global gaming industry in 2022 was estimated at nearly USD 347 billion. In fact, so big is the gaming industry so that it is estimated to be almost four times as much as Hollywood according to statista.com

The growth of the gaming industry is necessitated by the constant innovation of gaming consoles such as Xbox and PlayStation which command enormous popularity and demand globally

This has, in turn, driven up demand for gaming programmers. These are programmers who focus entirely on writing code for developing games on various platforms be it Windows, Mac, Linux, Android or iOS

To be a successful game developer, you need deep knowledge and understanding of gaming engines such as:

Unreal Engine
Godot
Cry Engine
Unity

And many more. Equally important, is the mastery of the following programming languages:

C and C#
Java Javascript
Python
HTML and CSS

System Hardware Programmers

System or hardware developers are programmers who focus on writing code using low-level programming languages specifically for firmware. This is a program or microcode that is embedded in non-volatile memory such as ROM (Read Only Memory). It contains instructions on how the computer will handle and manage hardware devices.

Firmware is an inherent part of the hardware and cannot be modified. Another example of firmware is BIOS (Basic Input Output System) which runs checks during booting and ensures all components are running as expected.

Widely used languages used by system or hardware programmers include:

Embedded C and C++
Java
Python

In addition to this, system programmers should be well acquainted with the ins and outs of system architecture and how various components communicate with each other on a hardware level.

So far, we have summarized some of the biggest and most common categories of programmers. While this is not a comprehensive list of all programmers in the industry, these programmers develop apps, tools, and services that we interact with on a daily basis.

Let’s now switch focus and have a look at System Administrators.

Who is a Systems Administrator?

System administrators are IT professionals who are in charge of an organization’s computing environment. They carry out a diverse mix of operations including ensuring optimal performance and maximum uptime of an organization’s core IT services and systems.
