Hello,
I won't waste your time with generic proposal/ my bio. I have gone through your project description to fixed the auto rotation in the app, If given a chance I would restrict the screen mode to portrait mode within hour of awarding of project. Looking forward to hear from you in the chat window to start working on the project.
Technology I would use,
Java, Kotlin, Manifest, XML
In past I have designed various screen and restricted their access to portrait/ landscape mode as required. Budget quoted is negotiable. If you have any queries, I would love to answer them to your satisfaction.
Best Regards,
Akash Goel
