Software creation of an AI-Based Marketing Assistant for Schools (MVP) Samiur was very patient with me as I was embarking on a project type that I had never done before. He explained everything to me and was keen to deliver the best he could even when challenges were thrown up. I am very happy with the software he has designed for me and I would certainly work with Samiur again. I believe his services are good value for money.
