Hello Sir,
I am Ionic developer with 4 year experience and have worked on Ionic since it's first release and done many projects on different version. We could develop the app on ionic 4/5, Since 5 is in development. So, I will develop the app in ionic 4. The only thing I need is API. I am perfectly ready to work in EST, no issue. I will corporate with your web developer synchronously. I recently completed one of the client work and looking for long term project after pandemic. But honestly, when I see your project I believe this one is great project. I will develop error free, optimised, encrypted app for security purpose. I might not have ratings on freelancer since I am new. But you won't be regretted. I have hope with you and your project, feel free to contact me anytime. Thank You for reading.
