Field Service Management SaaS Development for LATAM
Working with Muhammad was a great experience overall, and I'd happily recommend him. What stood out most was how quickly we got moving. From the very beginning, the process required very little upfront effort on our side when it came to design — Muhammad rapidly put together mockups that gave us something concrete to react to, which made our discussions productive and helped us align on direction fast.
Once we were ready to move forward, development went smoothly. The platform was well built, and it was clear he knew what he was doing technically. My one caveat is that the final details took a bit longer than I'd hoped, so if you're working toward a tight deadline on the finishing touches, it's worth planning for that. That said, given how much time we saved early in the process, it was a tradeoff I was happy to make.
If you value speed, strong communication, and someone who can turn ideas into something tangible quickly, Muhammad is a solid choice.

Build Wordpress Multi-event Event Ticketing Website
Do not trust Umair, you will be left bitterly disappointed and out of pocket.
I started the project for an event ticketing site with Umair back in April 2024 with a 6 month delivery date. It is now September 2025 with a product which is nowhere near what the scope was. It's full of bugs, incomplete functionality, missing functionality and features. His lack of communication has been horrendous, waiting days for a response at times and multiple chasers.
He has been extremely difficult to work with and I've been advised by third party developers that the code created by his developers is based on chatgpt hence the lack of quality. We are 18 months plus into this project and the site is unusable. I have to start the project from scratch due to the lack of quality.
The site doesn't work as it should and now I'm left with a half baked site which I need to pay another developer for. I have been at a financial loss losing business because of his poor quality work and extended period of time taken to complete the project, missed deadlines, poor communication, lack of responses and poor quality developers. I am beyond disappointed. I am shocked to see so many positive reviews as I have not received a good service at all. It's been diabolical to say the least and extremely stressful.
He is demanding payment for the final milestone which has not been delivered. I have paid him for frontend and backend work and later realised the work I have paid him for isn't fully there, he conned me. The code is lacking with functionality that should have been there and had promised was there. For some odd reason the UI was not coded into the site, they have been disorganised with no proper project management method.
The team are all over the place. His senior developer Haseeb is the worst developer I have ever come across, lacking basic knowledge in integrating mapbox showed me his lack of capabilities. It would take hours to troubleshoot on calls which I should not have needed to troubleshoot as I am not technical.
No QA had been completed and the team consistently kept pushing live incomplete work then lying and telling me it had been completed and was functioning. No QA, lack of mobile responsiveness, continuous errors on the site. Demanding payment for a product which hasn't been finished and is half complete with multiple issues.
I am beyond distraught. Save yourselves and don't go with Umair. Find better elsewhere.

KindPath Health - Mental Health Support Mobile App
Muhammad and his team delivered a high-quality product despite the complexity of our compact app. The workflows were intricate and pushed them to their limits, yet they remained professional, responsive, and focused on results. Their ability to translate complex logic into a smooth user experience was impressive. Highly recommend working with them, especially for projects with layered functionality and challenging requirements.
