Software Development Methodologies

Agile: A flexible and iterative approach to software development that emphasizes collaboration, customer satisfaction, and continuous improvement.
Waterfall: A linear and sequential approach to software development that emphasizes planning, documentation, and testing at each stage of the project.
DevOps: A set of practices that combines software development and IT operations to improve the speed, quality, and reliability of software delivery.

Software Design Patterns

MVC: A design pattern that separates an application into three interconnected components: Model, View, and Controller.
Singleton: A design pattern that ensures a class has only one instance and provides a global point of access to it.
Factory: A design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.
Observer: A design pattern that defines a one-to-many relationship between objects, so that when one object changes state, all its dependents are notified and updated automatically.

Software Testing

Unit Testing: A type of testing that focuses on individual units or components of code to ensure they work as expected.
Integration Testing: A type of testing that focuses on testing the interactions between different components or modules of an application.
Functional Testing: A type of testing that focuses on testing the functionality of an application from the user's perspective.
Performance Testing: A type of testing that focuses on testing the performance and scalability of an application under different loads and conditions.

Software Tools and Technologies

Git: A distributed version control system used for tracking changes in source code during software development.
Jenkins: An open-source automation server used for building, testing, and deploying software.
Docker: A containerization platform used for packaging, distributing, and running applications in a portable and scalable way.
Kubernetes: An open-source container orchestration platform used for automating deployment, scaling, and management of containerized applications.
