    Really happy with the work. I had a long list of ideas, and he helped me focus on the feature that mattered most. He understood the requirements, handled the date logic perfectly, and delivered ahead of schedule. The app feels much more useful now. Great experience and highly recommended!

    Dark mode reset to light on every reload. Fixed fast persists now for both guests and logged-in users (follows me across devices), no flash on load. Clear communication, no wasted words, and he explained the cause plainly (the choice was never being saved). Delivered a day early, and about money, it was great value. Highly recommended.

    Really impressed with Zain’s work. He understood the issue quickly, explained everything clearly, and kept me updated throughout. I especially appreciated how he took the time to educate me instead of just fixing the problem. He delivered early, was easy to work with, and provided great value. Would definitely recommend him.

    Came in thinking this was a tiny fix and found out our search had a security hole I had no idea about. It was explained clearly without making me feel dumb, the scope stayed exactly what we agreed, and it even caught bad data in our SKUs. Super responsive, finished early, and handled the barcode scanner...
