I am a new freelancer, but I am a programmer with more than 20 years of experience in PL/SQL.
I have created a payroll system, where the calculation has been developed in 100% PL / SQL, which have more than 10 package about 1000 line of code each.
I am good programmer using structured programming.
So, if you want create package, stored procedure, function, triggers o somthing else, I can do it for you.
I would like to know more about the project, I am imagining that what is required are stored procedures, package or triggers, for the application to consume them.
