Hello sir,
I am experienced with handling same type of issues where Teller Machine Gateway server is receiving ISO8583 message format and parsing it to take actions (i.e, Inquiry, POS Debit, ATM Debit etc) against the parsing result. And Java is the best way to handle such issues with port.
As, I am bidding after a long interval here, and I need work and good reviews for my profile, I am bidding for you with best price possible ($999) but again which is negotiable based on your project details.
It would be a honor for me if you deliver the project detail and let me know if you need to know anything.
Regards,
Shahidul
