Choosing your software development path 

There are several paths to becoming a developer or a programmer. Below are the 9 major types of software development paths. 

1. Website developer
2. Software application developer
3. Computer system engineer
4. Database administrator
5. Computer systems analyst
6. Software quality assurance (QA) engineer
7. Business intelligence analyst
8. Computer programmer
9. Network system administrator 

In this post, I’ll cover our chosen path, which is website development and I’m going to take a deep dive into how to become a website developer who specializes in WordPress. 

What is website development?

Creating a website is no different from building a house. 

It involves:

• Dreaming
• Planning
• Designing
• Building
• Maintaining 
• Optimizing 

While our focus on this post is only on the building part, you can breakdown website building or development into the following three subcategories: 

1. Front-end
2. Back-end
3. Full-stack 

Let’s explore all these three website development elements in detail. 

Website development fundamentals 

Before we jump right into the nuts and bolts of website development. I believe it is important to review the following website development fundamentals first, which are important for all types of website development. 

How the internet works

The Internet is a network of computers used to transfer data from one place to another. In easy terms, it is like a huge wire that connects different computers all over the world. 

Computers that are a part of this network have a special role to be online 24/7. When you search for something on the internet, your computer sends a request to your ISP (internet service provider) that connects you to DNS (domain name system)

DNS is like a giant address book that contains IP addresses of all the online websites. This is how you access any website by entering the website address in your web browser. 

And the interesting thing is that it all happens in a matter of a millisecond. 

How a website works

In order to access a website, first you need a browser. For example, Chrome, Firefox, and Safari are a few examples of web browsers.

When you access an IP address through your browser it receives those files in different languages such as:  

• HTML
• CSS
• JS

This explains that a website that we see is a result of the above three codes. All of these have different roles and responsibilities.

1. Front end

In simple words, a front end is what the website user sees, when he or she interacts with any website. 

And a front end developer is responsible for building, maintaining and improving a website design provided by your designer. Front end website developers transform a website design into an interactive live website using front end programming languages. 

Front end website development main skill requirements are:

• HTML 
• CSS 
• JavaScript
• Basic understanding of git, GitHub and version control.
• How to efficiently use the Unix command line.
• Troubleshooting and debugging skills.

Role of HTML, CSS and JavaScript in web development

JavaScript 

You need Javascript to add dynamic & interactive features to your websites such as sliders or popups. It works like white goods in your house, which extends the functionality of your brick & mortar to make it more fun and comfortable.  

Important Javascript skills a good front end developer needs:

Bootstrap

 

Bootstrap is the most popular front-end library. It comprises numerous pre-written codes that you can simply drag and drop into your site to make designing easier. It is free and open-source.

A few things, which you must learn to get the most out of Bootstrap as s front end developer are:

One important function of Bootstrap is that it makes the websites responsive and adaptable. Moreover, it has pre-styled elements that you can use with little customization and minimal effort. It saves you the trouble of writing the entire code. 

Document object model (DOM)

According to Wikipedia, The Document Object Model is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree.

• The tree structure of HTML based websites
• How to traverse through the document using object notation

You need a strong understanding of the following things.

• How to use git for version control and collaboration
• Git forking, branching and cloning

What is WordPress development?

If you know how to cook, you most probably can cook meat as curry, grill, or BBQ it. However, if you would like to master how to grill meat, you probably need to focus more on grilling meat to improve your specialized cooking skill.

General website development is similar to cooking & WordPress development is like mastering your favorite way of cooking meat. 

WordPress development is still website development. However, your focus is on one way of building a website, which is the most popular way of building modern websites at the time of writing this. 

Main WordPress development areas are: 

1. Themes Development
2. Plugin development
3. Core Development

How to become a WordPress developer 

“If you chase two rabbits, you’ll not catch either one.” Russian Proverb  

It is important to have a complete overview of website development fundamentals and then choose your path that resonates with your personal skills the most. 

For example, if you are an artist type, theme development might be the best way to specialize in. However, if you are more of a logical guy, you can have a great future in plugins and core WordPress developments.

And if you are a fan of James Bond, you may want to go for a full-stack WordPress development by learning front & back end development.  

WordPress theme development 

WordPress theme development means creating your own WordPress themes from scratch. 

WordPress theme development allows you to create your own theme with a custom look, feel, and color combination. Furthermore, you can design your own layout and page/post styles. 

There are various stages in theme development as well. Following are the required skills for each stage.

Continuous personal & professional development plays a vital role in your development career success as a WordPress developer, no matter how skilled you become technically. 

Disclaimer: Please note I’m not a web developer. However, I have several young WordPress developers on my team. I researched and created this roadmap to help them become a better WordPress developer. This roadmap is a work in progress, which I’ll be updating continuously as per feedback & experiences.
