Here's What Colleagues Are Saying

I was always impressed by Djuro's ability to complete the work assigned to him on time. Djuro not only met deadlines but also explains his programs in a way that non-experts can easily understand. This skill came in handy when he presented his programs to clients who weren't particularly tech savvy. Also his dedication to work and constant improvement were very remarkable. I had a lot of fun working with him and I've learned a lot
Uros Milivojevic

I had the pleasure of working with Djuro for two years collaborating on several iOS projects. He highly knowledgeable in his field of iOS mobile development and, at the same time, is capable of quickly understanding the client requirements. I am glad to have found him and now I can outsource any project to him without a worry and at a reasonable cost. I highly recommend Djuro Alfirevic.
