When hiring a web developer or software programmer, there are several hard coding skills that are considered non-negotiable due to their fundamental role in modern web development and software engineering. Here’s a detailed list based on industry standards and current practices:
WEB DEVELOPMENT SKILLS THAT ARE MANDATORY
Front-End Skills:
HTML5:
Mastery of Structure: Ability to create well-structured, semantic HTML for web pages.
Forms and Accessibility: Knowledge of form elements, semantic tags for better SEO, and accessibility features.
CSS3:
Layout and Design: Proficiency with Flexbox, Grid, and responsive design principles.
Animations and Transitions: Understanding CSS animations, transitions, and keyframes for interactive elements.
Preprocessors: Familiarity with Sass or Less for more efficient stylesheet management.
JavaScript:
Core Concepts: Deep understanding of JavaScript syntax, functions, closures, prototypes, and ES6+ features like Promises, async/await.
DOM Manipulation: Expertise in manipulating the DOM for dynamic web content.
Event Handling: Ability to manage user interactions through event listeners.
Frameworks/Libraries:
React,
Vue.js, or Angular: At least one major JavaScript framework for building single-page applications (SPAs) or complex user interfaces.
State Management: If using React, understanding of Redux or Context API; for Vue, Vuex; for Angular, NgRx or RxJS.
Version Control:
Git: Proficiency in Git for version control, including branching, merging, and resolving conflicts.
Back-End Skills:
Server-Side Languages:
Node.js (JavaScript): For full-stack developers or back-end with a focus on JavaScript.
PHP, Python, Ruby, Java: At least one of these for traditional server-side programming, with knowledge of frameworks like Laravel (PHP), Django/Flask (Python), Ruby on Rails, or Spring (Java).
Databases:
SQL: Basic to intermediate knowledge of SQL for relational databases like MySQL, PostgreSQL.
NoSQL: Understanding of when to use NoSQL databases like MongoDB for document storage.
API Development:
RESTful or GraphQL: Ability to design and implement APIs, understanding of HTTP methods, status codes, and authentication mechanisms.
Server Management:
HTTP/HTTPS: Knowledge of server protocols, including setting up SSL/TLS for secure connections.
Testing:
Unit Testing: Writing unit tests with frameworks like Jest (for JavaScript), PHPUnit (for PHP), or PyTest (for Python).
SOFTWARE PROGRAMMING SKILLS THAT ARE NON-NEGOTIABLE
Algorithms and Data Structures:
Fundamental Knowledge: Ability to solve problems using basic to advanced algorithms and data structures.
Object-Oriented Programming (OOP):
Principles: Mastery of OOP concepts like inheritance, polymorphism, encapsulation, and abstraction.
Design Patterns:
Implementation: Knowledge of applying design patterns to solve common software design problems.
Debugging:
Skills: Competence in diagnosing and fixing bugs in code, using debuggers, and understanding error traces.
Security:
Practices: Understanding of common web vulnerabilities (XSS, CSRF, SQL Injection) and how to mitigate them.
Performance Optimization:
Optimization Techniques: Knowledge of code optimization, caching strategies, and database query optimization.
Cross-Field Skills:
Command Line Interface (CLI):
Proficiency: Comfort with using Bash or PowerShell for scripting and basic system administration.
Package Management:
npm, Composer, pip: Familiarity with package managers for managing project dependencies.
Build Tools and Task Runners:
Webpack, Gulp, Grunt: For automating tasks like bundling, minification, and running tests.
Continuous Integration/Continuous Deployment (CI/CD):
Understanding: Experience with tools like Jenkins, GitHub Actions, or GitLab CI for automating testing and deployment.
These skills form a baseline for what one might expect from a competent web developer or software programmer. However, depending on the specific job role or project, additional specialized skills might be required. It's also important for developers to continuously update these skills as technology evolves.
