      UI/UX Design Review from Neil Serebryany

      I had the pleasure of working with RNO1 on a web transformation project in CalypsoAI and couldn't be happier. Right from the start, it was clear that they had a very skilled workforce, that had data architects as well as UX designers on board.They gave us a first implementation of your platform to work before your deadline and this demonstrates that they are conscious of time and the quality they want to offer. The look and feel design talents of RN01 are on par with the finest User Interface design and UX skills, moreover, the backend programming is also excellent.Most noticeable was their ability to fit into our working environment and improve the efficiency of our team while advancing the projects. Well done and organized they ensured the entire period was smooth and productive.As for web design and CMS development, I have no reservations in recommending RN01. They can really be considered as an innovation partner.

      Amy Marohn's Review Sourced from Google

      Lindsey & her team at Shameless Promotion are a rare find! Their collective technical and marketing skillset is unparalleled; their ability to adapt and customize services based on clients' needs - unheard of in the mainstream marketplace; their level of professionalism, customer service and follow-through is exceptional. I am eternally blessed and grateful as a sole proprietor & middle-aged business owner to have some of the greatest brains in the marketing industry as a support. Highly recommend. I'd give them more stars if I could. THANK YOU!!
