Relaunch Mobile App Revamp

I need a mobile app revamp to improve user experience and add new Gen-AI features, including Deepseek, which currently has ChatGPT integrated. The main objectives are to relaunch from a dormant Flutter/Firebase app, enhance/update older libraries and navigation, refine typography and visuals, and refine features like push notifications, social media integration, and in-app purchases.

The Main Goal is to relaunch to allow users to sign up on both Android and IOS. It was launched but was not renewed due to the business model change.

Key Requirements: Having experience with GoFundMe, Bloomerang, and Salesforce would be desirable.
- Improve layout and navigation for better usability
- Refine typography and visuals for a modern look
- Add push notifications, social media integration, and in-app purchases
- Restart and renew old app versions

Ideal Skills and Experience:
- Proven UI/UX design expertise
- Proficiency in mobile app development
- Experience with push notifications and social media APIs
- Familiarity with in-app purchase implementation

Google GCP, Google APIs, Google payment, Apple Pay, Python, Flutter, Firebase, and PostgreSQL experience required.

Please provide a portfolio showcasing similar work. Looking forward to your proposals!
