All the programming a software engineer does must be scalable, adaptable and maintainable. Technology advances by leaps and bounds, and so the code must have a forward-looking approach. There should attention to detail, and an eye on the larger picture. A designed software must be immune to tech changes. In the long-run, a machine-language-based solution must be scalable, adaptable and maintainable. The more the solution is modular, the better it is.
It is important to have the knowledge of the domain where the code will be deployed. If a developer understands the context, the programme will be both useful and valuable. A programmer, as a beginner, may not have complete domain knowledge, but should know more about the domain over a period of time.
A programmer must master a portfolio of technologies which can be put to use while developing products and solutions. A full-stack programmer is a valuable asset.
Programmes are infected by virus or bugs. Its presence in a place indicates that it may be present elsewhere too. It is better to fix the root cause. Youngsters must consult the senior colleagues while doing so. There are repetitive patterns in the code, and the bug too is likely to be present in such repetitions.
