    • Connect front-end and back-end components. Ensure smooth communication and data flow between them.
    • Integrate third-party APIs if required. This can include payment gateways, analytics, or other essential tools.
  • Adopt Agile Methodologies: Use sprints to break development into manageable phases. Regular reviews ensure alignment with project goals.

Example:

If building a SaaS for e-commerce, developers might focus on modules like inventory management, payment gateways, and customer analytics. Each module should be independently testable and scalable.

5. Testing and Quality Assurance (QA)

Testing ensures the application works as intended and meets quality standards. Different testing methods are employed to detect and resolve issues.

Types of Testing:

  • Unit Testing: Verify the functionality of individual components. This helps catch bugs early in the development process.
