Monthly React Native App Maintenance -- 2

I'm in need of a skilled and committed specialist for the ongoing maintenance of my react native mobile application. I require a professional who can ensure that the front-end runs smoothly while managing the C# backend. The routine monthly maintenance should entail the following tasks: Main tasks include: - Responding to App Store and Google Play updates and the infrastructure supporting the app. - Bug fixes: There maybe occasional glitches that need rectifying, ensuring the app is running smoothly without disruptions. - Performance optimization: The application’s performance needs to be optimized for speed and responsiveness. - Upgrading libraries: Software libraries must be updated frequently to secure optimal app performance and efficiency. - Preparing and submitting software updates on both platforms. - Duplicating pre existing features on the app (code already written) with different headings to support app grow and submitting for approval. - Feature enhancements: I'm always keen on improving the app's functionality, and I believe an upgrade of its features is a step in the right direction. I also need someone who is familiar with database integration, since the application is connected to a database. The ideal freelancer for this task is someone with proven experience in react native applications and upkeep of C# backend. Has a knack for identifying and fixing bugs, and possesses an understanding of performance optimization techniques and modern software libraries. Any previous experience in dealing with database integrated systems will be an added asset. I’m looking for someone who can ensure the application’s optimal functionality monthly.
