Hi,
I am developing applications in Java platform with Access,Oracle,Sql Server as back end database.
I have completed several similar applications like Reservation System, Seminar Management System, Book Store etc for other clients.
Please check my portfolio and previous works for reference. I assure you of quality product following Standard software methodologies,
3-tier architecture and suitable design patterns so that the system becomes easily maintainable and extensible.
My recent projects are https://www.freelancer.com/projects/PHP-Software-Architecture/database-design-for-daily-cash.html
and https://www.freelancer.com/projects/PHP-Software-Architecture/Help-writing-accounting-software-using.html
