Roll Dice - Mobile App

Your satisfaction is my success

I was on GitHub looking for open source dice for my new Craps mobile app when I discovered Andy's work. Andy was able to implement his dice into my Swift app. He was reliable and professional.

I approached Andy because I needed a website for my YouTube brand King Apdo. Andy Kotov made the design and production process easy and rewarding since I didn't know much about websites. He is an easy and pleasant person to talk to.

I have worked with Andy from Nov 2021 to June 2022 within the framework of an SEO Project. He was responsible for providing coding support to build and launch a crypto SEO site. I am really impressed by the quality of services I received from Andy.
