Hello, gentleman I am a senior Mobile/Web app developer,
I understand what you are looking for now, so I have to make Firebase cloud function(Like Endpoint) and define the localStorage structure?
If you have any guidance about pricing or need to increase or decrease the scope of work, kindly just let me know.
I appreciate the opportunity to send you this proposal and I look forward to working with you!
Sincerely,
Jee Szes L.
