    I was looking for a freelancer to help fixing some issues and maybe working on some new features on my website. I had to look for another freelancer as two other agencies just couldn't get the job done... Sergio did an amazing job working on the tasks I had outlined! He fixed the issues quickly and with great care and he worked on new features, too. It is just so great to have a freelancer who just works on the tasks without endless discussions about why things need to be done a certain way. He tried his best to understand the requirements (which were rather complex) to make sure to implement the code correctly. When I found a critical bug he stopped his work immediately and took care of the bug so we could be up and running. He's just a great freelancer to work with and I'd definitely recommend him to anyone! I'll definitely work with him again!
