Hello,
I'm Janos and would like to help you on this. I understand the requirements and can deliver this within 3 days max (or much sooner). Do you have any information on the server-side that I could check?
I'm ready to move forward with this now, delivering a robust application with proper error-handling and logging, sufficient comments and developed using industry standards as well as I'll be available for future enhancements at any point.
I look forward to working with you.
Kind regards,
Janos
