How to Become a Web Developer
Build real products for the web. One of the highest-demand skills globally.
Overview
Web development is consistently one of the most in-demand skills in the global job market. Every business needs a digital presence, and the people who build and maintain that presence are web developers. The field is broad: front-end (what users see), back-end (server logic and databases), and full-stack (both) all share the same foundation.
This roadmap was curated by Jason Sadiki, a Technical SEO Specialist and Web Developer who has built web products professionally for over seven years. The course selection is opinionated: it cuts through the noise and focuses on the specific languages, frameworks, and tools that appear most consistently in South African and international junior developer job postings. The roadmap is challenging but entirely achievable through self-study.

The Roadmap
Build the Front-End Foundation: HTML and CSS
4–6 weeksEvery web page you have ever visited is built on HTML and CSS. HTML defines the structure and content; CSS defines the appearance and layout. These are not optional stepping stones; they are the permanent foundation of everything you will build as a web developer. This stage takes you from your first page to responsive, production-quality layouts using modern CSS techniques.
Web Development with HTML and CSS for Beginners
Stage milestone: You can build a fully responsive multi-page website from scratch using HTML5 and CSS3, with no frameworks or templates.
Learn a Back-End Language
10–12 weeksFront-end skills make you a designer. Back-end skills make you a developer. In this stage you will learn server-side programming using either PHP with MySQL (the most widely deployed stack in the world) or Python with Flask (increasingly preferred in modern development). You will learn how to handle user input, query databases, manage sessions, and serve dynamic content: the core mechanics of every web application.
Diploma in Application Development Using PHP and MySQL
Diploma in Scalable Python Web Development Using Flask
Stage milestone: You have built a functioning web application with user authentication, a connected database, and at least three dynamic pages.
Add JavaScript for Interactive Front-Ends
8–10 weeksJavaScript is the programming language of the browser. It is what makes web pages interactive: form validation, dynamic content updates, animations, and the entire ecosystem of modern front-end frameworks (React, Vue, Angular) are all built on JavaScript. This stage focuses on core JavaScript and its application in e-commerce and web development contexts.
Stage milestone: You can add interactive behaviour to a web page using vanilla JavaScript, and understand how JS communicates with back-end APIs.
Learn DevOps Fundamentals
4–6 weeksModern web development does not stop at writing code. Junior developers are increasingly expected to understand how their applications are deployed and kept running. This stage covers DevOps fundamentals: what containerisation is, how Docker works, CI/CD pipelines, and the basics of getting a web application from your local machine into a production environment.
Stage milestone: You can containerise a web application using Docker and describe the basic steps required to deploy it to a cloud server.
Certifications Worth Getting

Free CPD-accredited diploma. Useful as a visible credential on your CV alongside a strong GitHub portfolio.
Portfolio Project Ideas
Employers want proof, not promises. Build at least two of these before applying for jobs, and document each one publicly on GitHub or a personal portfolio.
- 1
Personal portfolio website: a responsive, multi-page site built entirely in HTML, CSS, and JavaScript with no templates
- 2
Full-stack web application: a CRUD application (e.g. a task manager or blog) with user authentication, a MySQL or SQLite database, and a PHP or Python back-end
- 3
E-commerce product page: a responsive product listing and detail page with a JavaScript shopping cart
- 4
Dockerised app: take any of your existing projects and containerise it with Docker, with a README explaining the setup
- 5
REST API: build a simple JSON API in Flask or PHP that supports GET, POST, PUT, and DELETE for a resource of your choice
