Endorsements from past clients

"Recommend Rehan - absolutely! We hired Rehan to expand the functionality of our WALLTAT vinyl wall decal store by adding an AI assistant for image generation. He took our requirements and generated a solid prototype that we reviewed, tweaked a bit and then Rehan installed it on our existing Wordpress site for us. It was an easy and almost effortless project on our part because Rehan did all the heavy lifting for us. I would highly recommend Rehan for your next AI project."

"I hired Rehan to help me produce professional AI images in my online business using advanced custom ML models, I was very impressed with his level of creativity, professionalism, and experience. He genuinely cared about the success of my business and provided recommendations and feedback as if it's his own business. He went above and beyond to complete my project and he spent a lot of time with me going over the details of the solution and answering a ton of questions from me. I highly recommend Rehan and looking forward to working with him again. "

"Rehan helped us build a quick MVP that's an AI powered webapp hosted on Firebase. He understood the concept quickly and has all the developer skills needed to build and deploy the application. I also appreciated his determined character when faced with obstacles along the way. He's eager and determined to deliver even when the going gets bumpy while maintaining a positive spirit. We'll continue to work with him for the long term.."

"It has been an outstanding experience working with Rehan. I have worked with about 150 different freelancers and this was a really great experience. Normally I avoid freelancers from India and Pakistan since I have so many experiences working with freelancers from those countries that it is difficult to communicate with. With Rehan, it was totally different. He speaks perfect English. Most important, he is lightning sharp. He understands the business and the problem we wanted to solve and could turn that into IT solutions. Extremely skilled and probably the easiest IT person to communicate with that I have worked with. That combination of communication and IT skills is rare!""
