A payroll system that I wrote using Swing in Java programming language I hope you will find it useful.
I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me at the following email address for further details. If you want to advertise on my website, kindly contact me also at my email address also. Thank you.
My email address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com
