Well, achieving "bug-free" code will probably be a dream since all our code are dependant on other libraries and how much ever secure our code is, we cannot assert the same for the underlying libraries. What can be done is to continously monitor for problems, and whenever it arises, fix them according to its priority. One other major point which this article misses is the engineer's stress factor. You take the best engineer and put him under immense pressure and unrealistic goals, you are inevitably going to get bad code. The company's work policy is also a determining factor for "bug-free" (in quotes) code. As Hussein Nasser says, you either code fast or get fast code, you don't get both.

Have pre-commit checks so that every git commit passes through proper formatting and coding standards check. Educate new members and junior developers about your development workflow.

1. Input Validation: Validate all user inputs on the server-side to prevent common security vulnerabilities, such as SQL injection, cross-site scripting (XSS), and code injection attacks.
