Software Product Engineering is the process of designing, developing, and maintaining a complete software product from ideation to launch and beyond. The product development lifecycle involves various stages, such as product ideation, planning, product design, development, testing, deployment, and maintenance. The focus is on building scalable, high-quality, and user-centric software products that address a specific market need and drive business growth.

This includes customizing existing software or building new applications from scratch to meet the unique needs of a customer. The focus is on solving a particular problem or streamlining a business process through a bespoke software solution.
