So you want job security in software development. Whilst your colleagues build maintainable, scalable systems that any competent developer could understand and modify, you're about to learn how to create complex systems that your organisation will never dare let you go. After all, who else could possibly understand the intricate web of dependencies you're about to weave?
The cruel irony of software development is that the better you build something, the less valuable you become. Well-architected systems with clear documentation, comprehensive tests, and intuitive design patterns practically maintain themselves. A junior developer can jump in, understand the codebase quickly, and start contributing meaningful changes. Meanwhile, the poorly-built system that requires constant nurturing, mysterious deployment rituals, and deep knowledge of its Byzantine internals? That's the one that comes with job security.
