1. How do you ensure your code’s safety and speed?

2. How would you describe the process you use for writing a code from inception to delivery?
Inception – unit test – code – run tests – commit – run tests – deploy

3. How do you ensure that the code you write has the ability to manage different kinds of error situations?

I use mostly logs and profiling tools depending on the situation.
