    Programmers (developers) utilize a programming language, which is a computer language, to communicate with computers. It is a set of guidelines created in any particular language (C, C++, Java, Python) and developed to carry out a certain task.

    2. Object-oriented programming

    A computer programming paradigm known as object-oriented programming (OOP) arranges the architecture of software around data or objects rather than functions and logic. An object is a data field with particular characteristics and behavior.

    3. Database architecture

    A database architecture represents a DBMS design. It aids in the database management system's creation, growth, use, and maintenance. Due to the development of the DBMS design, the components of the system can be segregated individually, and each can be modified accordingly.

    4. Agile and Scrum project management

    Scrum is one of the agile approaches created to help teams deliver a product incrementally and iteratively. Its emphasis is on using an empirical approach that enables teams to react quickly, effectively, and efficiently to change. It is frequently referred to as an agile project management framework.

    5. Operating systems

    An operating system (OS) is a type of system software that controls how computer hardware and software resources are used and offer basic services to other software applications.

    6. Cloud computing

    Providing computer services over the Internet (the "cloud"), encompassing servers, storage, databases, networking, software, analytics, and intelligence, is the purest understanding of cloud computing.

    7. Version control

    The process of monitoring and managing software code changes is known as source control, commonly referred to as source control. As frameworks have grown, version control systems enable software teams to work more rapidly and wisely.

    8. Design testing and debugging

    Testing ensures and verifies that software or applications are free of bugs, meet all technical criteria as determined by their design and development, and effectively and efficiently satisfy user requirements while managing all exceptional and boundary instances.

    Debugging is the process of correcting a software bug. It is the process of locating, examining, and eliminating errors. This activity starts when the program doesn't work as it should and ends when the issue has been fixed and the software has been tested successfully.

    9. Attention to detail

    Paying attention to detail can take many forms for a technical individual, such as a software engineer or software architect. It might refer to code quality, readability, performance, unit test coverage, or detailed commit notes.

    Role and Responsibilities of a Software Engineer

    Software engineering is an integrated field that combines multiple aspects of development. A software engineer is assigned multiple roles and responsibilities, most of which are related to mastering different programs. Some of these are as follows:
