Hi,
I’m an experienced Web-App developer with years of experience in the field.
As my understanding, you require a cloud-based app that needs to be secure and reliable. For these requirements, my preferred language would be JavaScript for its proven security and reliability in the field.
But, as there are not many details mentioned in the offer, I would like to ask you to discuss the details in private messages.
I have a fairly open timetable right now and can start working within hours. I can guarantee you unlimited revisions until you are fully satisfied with the work I have done. Feel free to message me anytime for any questions you may have in mind.
Also, I'm new on this platform so feel free to have the joy of cheap prices for the highest quality.
