Developer, or engineer, is not any different from a skillful craftsman. They polish on the code they write, making sure it is robust and reliable.

And like any skillful worker, they possess their own set of tools to do their work. And what's more, they have their set of "standard" in defining what is good, or not.

Me as a veteran in the industry for years. I have also developed my own standard and working approach, towards fulfilling and leading the development.

And I sum this up as "Devlosophy" - the philosophy I believe in software development.
