Website for my newly founded music publisher's (online payment & easy changements needed)
March 28, 2022 - April 29, 2022
"To start with, Sergio is a very nice and authentic guy. That alone already makes the work process fun and uplifting. he is also very capable and finds solutions to anything. I very much appreciate his never ending patience for changing little details that in the end make the difference. he answers as quickly as his workload permits him and is open to teach you how to do things yourself, if that's what you're looking for. Sergio takes the time to have a video conference whenever that makes things easier. Even after the payment he still engaged just the same to improve little matters that came up over time. I'll be contacting him for any website related issues or projects in the future.
