Web Accessibility

Understanding web accessibility guidelines (such as WCAG) and implementing accessible features in your websites ensures that people with disabilities can access and use them.

Testing and Debugging

Proficiency in testing methodologies and tools, such as unit testing frameworks (e.g., Jest or Jasmine) and browser testing tools (e.g., Selenium or Cypress), helps you identify and fix bugs in your code.

SEO Principles

Basic knowledge of Search Engine Optimization (SEO) principles and best practices helps you optimize websites for better visibility in search engine results.

Fron-tend Performance Optimisation

Understanding techniques to optimize front-end performance, such as code minification, script bundling, and reducing HTTP requests, can enhance the user experience.

Front-end Security

Knowledge of basic web security principles (e.g., Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF)) and best practices for securing front-end code can help protect against common vulnerabilities.

Responsive Email Development

Familiarity with HTML email development and email client quirks is valuable if you want to work on email marketing campaigns or newsletters.

Design Tools

Basic proficiency in design tools like Adobe Photoshop or Sketch can help you collaborate effectively with designers and translate design assets into web components. 

The specific skills required may vary depending on the job and the company you’re applying to. However, possessing a solid foundation in these front-end development skills will significantly increase your chances of securing your first web development job. 

Back-End Development Skills for Your First Job 

To secure your first web development job as a back-end developer, you must possess solid back-end development skills. Here’s a detailed list of back-end development skills that can help you get started: 

Programming Languages

Proficiency in at least one back-end programming language is essential. Common languages for web development include:

Python: Known for its simplicity and versatility, Python is widely used in web development with frameworks like Django or Flask.

JavaScript (Node.js): With the rise of Node.js, JavaScript can now be used as a server-side language, making it a popular choice for back-end development.

Ruby: Ruby, coupled with the Ruby on Rails framework, is known for its productivity and ease of use.

PHP: Despite its reputation, PHP remains widely used in web development, especially with frameworks like Laravel or Symfony.

Java: Known for its scalability and robustness, Java is commonly used in enterprise-level web applications.

Web Frameworks

Familiarity with back-end web frameworks can accelerate your development process and provide structure to your projects. Some popular frameworks include: 

Django (Python): A high-level Python web framework known for its batteries-included approach, robustness, and scalability.

Ruby on Rails (Ruby): A full-stack Ruby framework that emphasizes convention over configuration, enabling rapid development.

Express.js (Node.js): A minimalist web framework for Node.js, enabling fast and scalable development of web applications.

Laravel (PHP): A PHP web framework that follows the MVC (Model-View-Controller) pattern and emphasizes clean, elegant code.

Databases and SQL
Proficiency in working with databases is vital for back-end development. Familiarise yourself with: 

Relational Databases: Knowledge of SQL (Structured Query Language) and relational databases like MySQL, PostgreSQL, or Oracle is essential for data management. 

NoSQL Databases: Familiarity with NoSQL databases like MongoDB or Firebase can be beneficial for handling non-relational data and scalable applications.

API Development

Understanding how to design, build, and consume web APIs (Application Programming Interfaces) allows you to create robust, scalable, and interoperable systems. 

RESTful APIs: Familiarity with REST (Representational State Transfer) principles and best practices for designing RESTful APIs are important.

API Documentation: Knowledge of documenting APIs using tools like Swagger or Postman can enhance collaboration with front-end developers or third-party integrators.

Server-Side Frameworks

Apart from web frameworks, familiarity with server-side frameworks can enhance your back-end development skills: 

Express.js (Node.js): A flexible, minimalist framework for building web servers and APIs using Node.js.

Flask (Python): A lightweight Python framework that provides tools and libraries for building web applications.

Authentication and Authorisation

Understanding user authentication, session management, and authorization mechanisms is essential for building secure web applications. 

Familiarity with JSON Web Tokens (JWT), OAuth, or OpenID Connect is valuable in implementing secure authentication and authorization processes.

Caching

Knowledge of caching mechanisms and tools (e.g., Redis or Memcached) helps optimize application performance by reducing database load and improving response times.

Web Security

Understanding common web security vulnerabilities (e.g., Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), SQL injection) and implementing security best practices is crucial for protecting user data and preventing attacks.

Server Administration and Deployment

Basic knowledge of server administration, Linux/Unix command line, and deployment tools (e.g., Docker, Heroku, AWS) are valuable for managing and deploying web applications.

Testing and Debugging

Proficiency in testing methodologies, unit testing frameworks (e.g., Mocha, PHPUnit), and debugging tools helps identify and fix issues in back-end code.

Version Control

Familiarity with version control systems like Git enables efficient code management, collaboration, and tracking of changes.

RESTful Architecture

Understanding the principles of REST and designing systems that adhere to RESTful standards promotes scalability, modularity, and interoperability.

Microservices

Knowledge of the microservices architecture pattern, including building and integrating microservices, allows you to create scalable and maintainable back-end systems.

Message Queues and Event-Driven Architectures

Familiarity with message queue systems (e.g., RabbitMQ, Kafka) and event-driven architectures helps build highly scalable and asynchronous systems.

Performance Optimisation

Understanding techniques to optimise back-end performance, such as database query optimisation, caching strategies, and code profiling, enhances the scalability and responsiveness of web applications. 

While this list covers essential back-end development skills, the specific skills required may vary depending on the job and the company you’re applying to.
