CEO @ Hookah Hutt
"In the 8 years I've been using Upwork... I have never had more pleasure working with a freelancer than I did with Mladen. I found him to be intelligent, patient, skilled and an overall nice guy to work with. He made the entire process of customizing our Shopify store smooth, easy and with minimum hiccups.
10 out of 10, highly recommend you work with him!"
CEO @ MIH Products
"There are a lot of Shopify developers out there, but most are not as talented as Mladen. He created a website for me from a wireframe, and he did a great job coding the Shopify modules so that I can easily customize them without using code.
I would highly recommend Mladen for any Shopify work - he did a great job. He gave me status updates without me having to ask, and he was able to meet the deadline. A+ :)"
Webmaster @ Diabetic Source
"Mladen is an exceptional freelancer to work with. We sought a highly-skilled and knowledgeable developer for our project, and he was exactly that. Mladen was extremely thorough in explaining our options for improving the speed of our Shopify site. He provided honest feedback about the scope of work required and was patient answering all of our questions throughout the project. He delivered the work as promised ahead of schedule. I look forward to working with him on additional projects. I highly recommend Mladen without reservation."
Digital Marketing Manager @ RUVE
"The second time that we work with Mladen and he has delivered perfect work and completed all tasks asked. We will work with him again in the future. I highly recommend Mladen for your Shopify store."
