From our very first conversations, he demonstrated an impressive depth of knowledge, providing clear workflows and solutions tailored to the specific needs of my project.
Communication was smooth and consistent throughout the entire process, and all deliverables were provided on time, allowing me to successfully launch the MVP.
The system and development work flawlessly, with all the necessary tools, APIs, and technologies perfectly integrated and coordinated. From the start, Norayr guided me through every stage, helping me stay organized and clearly explaining what was needed from my side and how to proceed.
Working with him has been an exceptional experience that exceeded my expectations, both in terms of the quality of the work and the professionalism with which the entire process was managed.
Without a doubt, I’ve found a true professional. His name is Norayr, and I will absolutely work with him again on future implementations and new projects.

WebRTC/Websocket feature bug
I had a pleasure working with Norayr from start to finish. He helped build a pair program feature for our platform. The code quality was excellent, communication was clear and consistent throughout, and everything was delivered on time without any chasing. He proactively solved problems and went above and beyond the original scope without being asked. Professional, reliable, and easy to collaborate with - I'd hire him again without hesitation.
