It's not an absolute necessity to have knowledge of full-stack web development to be a software developer. Software development is a broad field with various specializations, including web development, mobile app development, desktop application development, embedded systems, and more. Your choice of specialization should align with your interests and career goals. 🌐📱💻

If web development is your preferred path, then full-stack knowledge can be highly advantageous, as it enables you to work on both the front-end and back-end of web applications. However, if you are more interested in other domains of software development, such as mobile app development, game development, or data science, you can focus your learning efforts in those areas. The key is to build a strong foundation in the specific technologies and skills relevant to your chosen specialisation. By gaining expertise in your chosen domain, you can excel as a software developer and contribute effectively to your projects. The software development field offers a wide range of opportunities, so feel free to explore and find the niche that best suits your interests and career aspirations. 🚀🌟
