Do you own object-oriented programming? What OOP templates do you use in practice? Do you know how to work with GIT, MySQL? How much is the hour of your work?
I have a fair amount of experience (most of my career) on OOP using different languages. Git and MySQL is a standard on this industry, I do not meant to brag but I have mastered both of them. I typically charge $30 - $100 per hour depending on the nature and skills required by the project.
