Hello,
While appreciating the easiness and tidiness of JAVA code, it is hard on some levels when comparing performances, to accept the results, in my opinion this is the main reason, I would use C++ instead.
Hi, I'm MAHMOUD, a computer and systems engineer & certified data analysis professional.
What I recommend, as a first step is to analyze and designing the migration process before proceeding to the code changing step, this will insure, a safe migration process which preserves code capabilities, compatibility, and also a well-structured, well documented, migration process.
Feel free to contact me to discuss further, how I can help you,
things like, the application scale, application domain, libraries used, API's, Interfaces\templates, if there are available documentations, or it is required to document the application, and whether you are thinking of expanding the capabilities of the application, or changing the scope of some parts, or all of its underlying structure.
I'll be more than happy to help achieve a secure and successful migration process.
p.s. the price set and time period are only a place holders.
