If I were to say what is my best skill, I'd say my ability to spot errors. I can spot bugs, and errors, understand the cause of them and plan the best fixing method on the spot.
Error and Bug fixing requires a lot of deductive work, like Sir Arthur Conan Doyle
's Sherlock Holmes
. You have to be able to spot the error and analyze all the possibilites that might cause it and figure out the actual cause and the solution for such and error.
I understand how frustrating it is to have a live website with errors or bugs, and that is why I created this emergency service that makes you able to reach me at any time during day or night if you had a project with another freelancer or agency and found an error or a bug and need immediate fix.
