He was wonderful to work with and he is an absolute expert in Retool and FlutterFlow, the platforms we used for development. What was most appealing about him was that he was able to predict, without me explaining to him, how our app should look and function! In fact, I did very minimal Requirements Discussions with him. He is a pleasure to work with and I would highly recommend that you hire him for your project. I plan to do the same as soon as I line up my next project.

He was exceptional to collaborate with, demonstrating his expertise in Retool, which was the platform we use for our external app development. His ability to envision our application's structure and functionality without explicit direction was particularly impressive. In fact, I had only minimal requirement discussions with him. Working with him is a delight and I would strongly endorse him for your projects. I plan on hiring him again for my next projects.
