Frontend /backend Improvements of Website
Great experience working with this freelancer. They handled both front-end and back-end development efficiently and delivered exactly what was discussed. Communication was clear, they were responsive to feedback, and they were able to troubleshoot issues independently. Code quality was solid, and deadlines were respected. Would definitely work with them again for future development work.

FlutterFlow + Supabase Expert Needed: Debug Tenant Module & Ship to Production
Aziz is great, He handled every issue in the brief with precision, communicated clearly, and solved problems without drama. When FlutterFlow’s native bugs started blocking progress, he took initiative and rebuilt the affected features so the project could keep moving, no extra charges, no delays. He delivered exactly what was needed and protected the timeline throughout. I’ve already hired him again for the next app version and a separate project because he’s reliable, skilled, and genuinely easy to work with.
