Their communication was excellent—always timely, transparent, and easy to follow—which made coordinating even complex project details effortless.Technically, Abdul and his team exceeded expectations. They delivered a high-quality, robust app that not only met but often anticipated our needs. Even with my busy schedule and frequent change requests, CMolds was incredibly flexible, adapting quickly without compromising quality or deadlines.What truly sets Abdul apart is his responsiveness and ongoing support. Any questions or issues were addressed promptly, with practical solutions and clear explanations, making the entire process smooth and stress-free. Their client-focused approach, combined with deep technical expertise and creative problem-solving, makes CMolds a standout partner for anyone looking to develop an app. I highly recommend Abdul Wasay and CMolds to anyone seeking a skilled, reliable, and exceptionally accommodating development teamThank you so much!

Harmony and Derek Munroe's Review Sourced from Google
So far so good. I am still waiting on an issue with Apple but I am excited for what they have created for my app idea. From Roman getting me started and connected with the development team to Safwan orchestrating the software, listening and making the changes I want. It has been a positive experience. They are flexible and do things in a timely manner. Can't wait until it finally gets released.

Web Development Review from Alicia Qin
Ashesh Shah with his company Fusion Informatics company is fraudulent, he took money, didn't keep the contract, didn't complete the project, didn't refund, he didn't feel any sorry about it but threatened me, then disappeared. It is the nightmare every client doesn't want to have, don't use them! If there is an option to choose no star, I would choose no star!
