     • Python (widely used in data science, web development, and automation)
     • Java (used in large-scale enterprise applications)
     • C/C++ (used for systems programming, game development, and performance-critical applications)
     • C# (often used for desktop and enterprise applications, especially with .NET)
     • Ruby, Go, Swift, Kotlin, and PHP are other common languages depending on the domain.
   • Familiarity with multiple languages: Developers should be flexible and willing to learn new languages or frameworks based on project requirements.

2. Web Development Skills

   • Front-End Development: Knowledge of how to build user interfaces using:
     • HTML/CSS: For structuring and styling content on the web.
     • JavaScript (and frameworks like React, Vue.js, or Angular) for making dynamic web pages.
   • Back-End Development: Understanding of server-side technologies to handle the application's logic and database interaction, including:
     • Node.js, Express (JavaScript-based)
     • Django, Flask (Python-based)
     • Spring, Hibernate (Java-based)
     • Ruby on Rails (Ruby-based)
   • RESTful API Development: Creating and consuming RESTful APIs for communication between the front-end and back-end.

3. Database Knowledge

   • Relational Databases: Understanding of SQL and experience working with relational databases like:
     • MySQL, PostgreSQL, SQLite
   • NoSQL Databases: Knowledge of NoSQL databases such as:
     • MongoDB, Cassandra, CouchDB for handling unstructured or semi-structured data.
   • Database Design: Ability to design data models, create normalized schemas, write complex queries, and optimize database performance.

4. Version Control Systems (VCS)

   • Git: Proficiency in using Git for source code management. Understanding how to create branches, merge changes, resolve conflicts, and use platforms like GitHub, GitLab, or Bitbucket for collaboration.

5. Software Development Frameworks and Libraries

   • Knowledge of frameworks and libraries that help speed up development by providing reusable code. This can include:
     • Spring Boot (Java)
     • React, Vue.js, Angular (JavaScript)
     • Django, Flask (Python)
     • Rails (Ruby)
   • Familiarity with UI frameworks (e.g., Bootstrap, Tailwind CSS), and state management libraries (e.g., Redux).

6. DevOps and Continuous Integration/Continuous Deployment (CI/CD)

   • Familiarity with CI/CD pipelines, automated testing, and deployment tools to ensure efficient software delivery and maintain quality code.
   • Tools: Jenkins, Travis CI, GitLab CI, Docker (for containerization), Kubernetes (for orchestration), Terraform, and cloud platforms like AWS, Azure, or Google Cloud.

7. Operating Systems and Networking Basics

   • OS Knowledge: Understanding operating systems, including processes, memory management, and file systems. Comfortable with using Linux for development.
   • Networking: Knowledge of network protocols like HTTP/HTTPS, TCP/IP, DNS, and understanding how web servers and clients interact.

8. Testing and Debugging

   • Unit Testing: Knowledge of writing unit tests to ensure code works as expected. Familiarity with testing frameworks like JUnit (Java), pytest (Python), or Mocha (JavaScript).
   • Integration Testing: Writing tests that ensure different parts of your application work together seamlessly.
   • Debugging Tools: Experience with debugging tools and profilers to identify and fix issues in your code (e.g., Chrome DevTools, GDB, Visual Studio Debugger).

9. Algorithms and Data Structures

   • Core Concepts: Strong understanding of fundamental algorithms (sorting, searching, etc.) and data structures (arrays, linked lists, trees, hash tables, graphs).
   • Problem-Solving: Ability to approach and solve problems in an efficient manner, optimizing for time and space complexity (using Big O notation).

10. Security Practices

    • Basic understanding of common security threats (e.g., SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF)).
    • Awareness of securing applications, encryption practices, and handling sensitive data.

Soft Skills

1. Problem-Solving and Critical Thinking

   • The ability to break down complex problems into smaller components and find efficient solutions. A logical, methodical approach is essential to succeed as a developer.

2. Collaboration and Teamwork

   • Software development is rarely a solo effort. Being able to work effectively in teams is key. This includes collaboration with other developers, product managers, designers, and stakeholders.

3. Communication Skills

   • The ability to communicate clearly, both in writing and verbally, especially when explaining technical concepts to non-technical stakeholders or discussing problems with other developers.
   • Writing clear code comments, documentation, and README files.

4. Time Management and Prioritization

   • Software development often involves working on multiple tasks at once. Being able to prioritize tasks, manage deadlines, and handle unexpected issues is vital.

5. Adaptability and Willingness to Learn

   • The tech industry is constantly evolving. A great software developer is curious, adaptable, and eager to learn new technologies, tools, and methods.

6. Attention to Detail

   • Writing code that is correct, efficient, and bug-free requires attention to detail. A developer must test thoroughly and ensure that every component of the code is working as intended.

7. Mentorship and Knowledge Sharing

   • Ability to mentor junior developers, conduct code reviews, and share knowledge with teammates. Knowledge sharing is key for continuous improvement and collaboration.

8. Empathy and Emotional Intelligence

   • Understanding team dynamics, managing stress, and being empathetic to the needs of users and team members are essential to a productive work environment.

9. Patience and Persistence

   • Software development can be challenging, and problems may not have immediate solutions. Being patient and persistent is crucial for troubleshooting bugs or overcoming design challenges.
