Wear OS App Development

Phase 1 deliverables were completed and the codebase was provided as agreed. As the project evolved, my changes to scope resulted in pricing discussions that did not align with my expectations. I recommend clearly defining how scope changes will be handled and priced in advance for longer or evolving projects.

Highly recommended for anyone looking for a skilled Full Stack Developer developer!

Development of pet tracking app (we need experienced and professional UX/APP expert)

Bhatti's team is a very good mobile application team. They helped us create a mobile app using Flutter, that we will be launching on both iOS and Android platforms. The app works perfectly, and Bhatti also did QA, testing the app on multiple mobile devices to make sure everything runs smoothly. We are very happy with their work, and we highly recommend him and his team to anyone looking for a mobile app developer. Thank you, Bhatti, for all your hard work!
