Hi,
I can surely implement new design into the app as I had done 98% of similar work in past. I am a Full-stack developer holding 6+ years of experience working with Native iOS(Swift and Objective-C), Azure and working with React native and some Native components of RN from last 4+ Years. I have ability to work with Figma and associated design tools (Invision, Photoshop, Illustrator, etc.) and have excellent experience in Web/mobile app UI/UX design. I've designed and developed many apps including Taxi booking, Transportation, E-commerce, B2B, B2C, real estate, Online restaurant, Car Rental, Car Sell/Buy, Food delivery, and on all the other platforms with advanced functionality and eye-catching design works.
I am quite certain we have got the skills you are looking for. I have developed many mobile applications having varied functionalities and complexities including payment gateway integration, hardware integration (Health-care), social media integration, deals, cloud data storage, payments, beacons, analytics, location tracking, push notifications, messaging and communication.
@ Have you prepare any detailed document?
Lets initiate the chat to get more idea about the project and will also show you my previous work and can start work immediately.
Thank you..!
