First of all, the essential skill that I have is the efficient use of your computer and various software to do online transactions; being a virtual assistant means working remotely and to be able to transact with anyone, doing everything via digital means. From data entry, transcription, typing jobs, video calls, file conversion and submission, and many more.
To be honest, I may not be a jack-of-all-trades kind of virtual assistant. But I assure you that I could offer my said skills, then along the way, I'm eager to learn how to do other things that I'm assigned to do.
