ABOUT ME
Senior iOS Engineer
Senior iOS Engineer
15+ years of experience with iOS and over 190 iOS applications written in Objective-C and Swift.
16+ years of lecturing experience (iOS, OOP, Software Architecture)
Mentoring others is my first love - and I have a tone of experience in that field. I started teaching others math, electronics, and electrotechnics and after some time - I started working for a couple of IT schools where I teach iOS and teach people to think differently.

Djuro knows iOS and Swift very well. Strong subject knowledge with debugging skills.

Djuro is an incredible mentor. He understood my problem right away and started diving in to find the problem. Not only did he fix the issue, he also explained his thought process along the way, and showed me a bunch of resources to help me debug similar issues in the future. I will definitely be returning, and would highly recommend Djuro as a mentor!

Djuro is not only an expert in Swift but a extraordinarily gifted teacher. Over the course of 4 sessions he taught me how resolve issues, prevent them from occurring in the future, and answered any question I had promptly and accurately. I would highly highly recommend him as a codementor for iOS developers.
