Hi Gentleman,
I am a technology expert, more than a decade I am developing and delivering applications on Java based technologies. I am a certified Java professional. My logical thinking and problem solving skills are quite good. Currently I am developing several applications using Android, IOS, Core Java, Servlets JSP, Struts framework, Spring Framework, Restful Services, Spring Security, Springboot, Hibernate, JPA, MySQL, Oracle, MongoDB and Angular.js as Front End.
NOTE: I have gone through your class diagrams carefully. Minimum 2 days of effort is required. So I kept 3 days with one day buffer. Let me know if you are interested.
Thanks
Paul
